apparmor: Fix ref count leak in task_kill
[ Upstream commit 2cb54a19ac7153b9a26a72098c495187f64c2276 ]
apparmor_task_kill was not putting the task_cred reference tc, or the
cred_label reference tc when dealing with a passed in cred, fix this
by using a single fn exit.
Fixes: 90c436a64a6e ("apparmor: pass cred through to audit info.")
