[PATCH v2 27/29] staging/lustre/osc: glimpse lock should match only with granted locks

From: Andriy Skulysh A deadlock is possible during ccc_prep_size()->ldlm_lock_match() vs cl_io_lock() which is waiting for a matched lock and conflicts with already taken lock before ccc_prep_size(). It is better to send an additional lock request to avoid deadlock.
