Subject: afr: fixes to afr-eager locking

1. If pre-op fails on all bricks,set lock->release to true in
afr_handle_lock_acquire_failure so that the GF_ASSERT in afr_unlock() does not
crash.

2. Added a missing 'return' after handling pre-op failure in
afr_transaction_perform_fop(), fixing a use-after-free issue.

Change-Id: If0627a9124cb5d6405037cab3f17f8325eed2d83
fixes: bz#1561129
