AppArmor: fix oops in apparmor_setprocattr

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.
