apparmor: check label build before no_new_privs test
aa_change_profile() builds a replacement label with
fn_label_build_in_scope() before the no_new_privs subset check. The build
helper can fail and return NULL or an ERR_PTR, but the result was passed
to aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL()
check.
Reuse the existing target-label build failure handling immediately after
the build. This preserves the current audit handling while preventing the
subset helper from dereferencing an invalid label.
