afr: switch lk_owner only when pre-op succeeds
Problem: In a disk full scenario, we take a failure path in afr_transaction_perform_fop() and go to unlock phase. But we change the lk-owner before that, causing unlock to fail. When mount issues another fop that takes locks on that file, it hangs. Fix: Change lk-owner only when we are about to perform the fop phase. Also fix the same issue for arbiters when afr_txn_arbitrate_fop() fails the fop. Also removed the DISK_SPACE_CHECK_AND_GOTO in posix_xattrop. Otherwise truncate to zero will fail pre-op phase with ENOSPC when the user is actually trying to freee up space.
