apparmor: Use pointer to struct aa_label for lbs_cred

Browse source 
[ Upstream commit 37923d4321 ]

According to the implementations of cred_label() and set_cred_label(),
we should use pointer to struct aa_label for lbs_cred instead of struct
aa_task_ctx, this patch fixes it.

Fixes: bbd3662a83 ("Infrastructure management of the cred security blob")
