apparmor: make __begin_current_label_crit_section() indicate whether put is needed
Same as aa_get_newest_cred_label_condref().
This avoids a bunch of work overall and allows the compiler to note when no
clean up is necessary, allowing for tail calls.
This in particular happens in apparmor_file_permission(), which manages to
tail call aa_file_perm() 105 bytes in (vs a regular call 112 bytes in
followed by branches to figure out if clean up is needed).
