- a high priority request list is added into service;
- once a lock is canceled, all the IO requests, including coming
ones, under this lock, are moved into this list;
- PING is also added into this list;
- once a lock cancel timeout occurs, the timeout is prolonged
if there is an IO rpc under this lock;
- another request list is added into the export, used to speed up
the rpc-lock matching.

During ll_intent_lock(), server looks up parent and child, lock them, between these events parent could be deleted, then vfs_create may_access() fails with -ENOENT.

Then client intent disposition got DISP_OPEN_CREATE | DISP_LOOKUP_NEG | DISP_LOOKUP_EXECD | DISP_IT_EXECD, and the request got double free.

Solution: Clear DISP_ENQ_COMPLETE when we are going to release the intent (request cannot be reused anyway)

- 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;

- 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 imp_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;
