afr: fix race between __afr_eager_lock_handle and afr_wakeup_same_fd_…

…delayed_op (#4425) (#4426)

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.

Fixes: #4425
