…delayed_op (gluster#4425) Race between __afr_eager_lock_handle and afr_wakeup_same_fd_delayed_op will lead to stale inodelks, which may cause subsequent IO blocked. To avoid this race, set lock->release = _gf_true also in afr_wakeup_same_fd_delayed_op so that a new transaction can be correctly handled as expected in __afr_eager_lock_handle.
