act_ife: fix a potential use-after-free
[ Upstream commit 6d784f1625ea68783cc1fb17de8f6cd3e1660c3f ]
Immediately after module_put(), user could delete this
module, so e->ops could be already freed before we call
e->ops->release().
Fix this by moving module_put() after ops->release().
Fixes: ef6980b6becb ("introduce IFE action")
