  - fixes ost cleanup issue due to missed llcd_put() in the case ost does not receive disconnect from mds;

  - do not sleep on hanging llcd. Instead assert on it _after_ stopping recov_thread's ptlrpcd which should kill any remeining llcds;

  - fixes and cleanups, comments.

- fixes manual_umount_client() in conf_sanity.sh to handle --force correctly as it is used by number of tests (this part should be missed in tests porting);

- add assert before decref mgc refcounter;

- kill @rc in server_put_super() as it is not used;
- use OBD_FAIL_CHECK_ORSET in ptlrpc_check_set() to avoid assert;
- enable test_45 as it is working now.

- make sure that no new inflight rpcs may come after ptlrpcd_deactivate_import() for both
synchronous and asynchronous sending. To do so we make sure that imp_inflight++ is done only when
permission is granted by ptlrpc_import_delay_req() which makes decision should req be sent,
deferred or killed as import is not in the state to send it in observable future. For async
sending, rpc is only counted inflight when its added to sending or delaying list instead of just
adding it to set for processing.

This fixes assert in ptlrpc_invalidate_import() and as number of other issues;

- synchronize imp_inflight and the presence on sending or delaying list for ptlrpc_queue_wait()
case. So that, now it is guaranteed that if im_inflight != 0 we may always find hanging rpc either
in sending or in delaying list;

- make sure that in ptlrcp_queue_wait() we remove rpc from sending or delaying list and dec
inflight only after ptlrpc_unregister_reply() is done. This way we make sure that accounting is
correct. Rpc can't be returned to the pool or counted finished until lnet lets us go with finished
reply unlink;

- check for inflight and rq_list in pinger;

- comments, cleanups;

  - removes deadlock possibility by disabling rehash in hash_del() operations and moving hash_add()
    out of spin_locks when calling. Hash table has own mechanisms for protecting its structures and it
    also has hash_add_unique() method for using in concurrent run contexts;

    - fixed missed lh_put() in hash_add_unique() which led to extra refs in some cases (extra ref to
    export) and inability to cleanup;

    - fixed __lustre_hash_set_theta() which set @max theta into ->lh_min_theta;

    - in lustre_hash_rehash_size() disable rehash also for the case when new and old hash sizes equal
    in corner cases (max_size or min_size). Before this fix it could be possible to do needless
    rehashes when size is actually did not change but we do this expensive operation;

    - disable rehash in hash_add_unique() if no actual add happened since entry with the same key is
    already found in the table;

    - some cleanups in hash table code;
