apparmor: optimize current_label_crit_section() with needput

The {begin,end}_current_label_crit_section() has the same issue as the
{__begin,__end} version. That is the check to see if the label has
been updated in the end check forces an unnecessary memory barrier.
We can optimize this the same way we do with the {__begin,__end}
variant by passing in a local variable that carries the state
information from the begin check into the end check.

No functional change.
