AppArmor: fix oops in apparmor_setprocattr
commit a5b2c5b2ad5853591a6cac6134cd0f599a720865 upstream.
When invalid parameters are passed to apparmor_setprocattr a NULL deref
oops occurs when it tries to record an audit message. This is because
it is passing NULL for the profile parameter for aa_audit. But aa_audit
now requires that the profile passed is not NULL.
Fix this by passing the current profile on the task that is trying to
setprocattr.
