apparmor: fix refcount leak when updating the sk_ctx PUBLISHED

Description (CNA)

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix refcount leak when updating the sk_ctx Currently update_sk_ctx() transfers the plabel reference, unfortunately it is also unconditionally put in the caller.
