Description: MDS or OSS service threads fail startup with -24 (-EMFILE)
Details    : During startup under recovery, it is possible for service
             thread startup to fail in ptlrpc_start_threads() if one
             of the threads begins processing a request and then starts
             an additional thread.  This causes ptlrpc_start_threads()
             to try and start 1 too many threads and get an error.

during liblustre test during

mgc_llog_init() (lustre/mgc/libmgc.c)
  llog_initiator_connect(ctxt)

while in liblustre lib, it is defined as an empty function only return 0, while
in kernel lib, it set the context's loc_imp. And this context's loc_imp is
required after in llog_client_create().

This fix defines llog_initiator_connect() in both lib (kernel version and
liblustre version)
