netlabel: fix the netlbl_catmap_setlong() dummy function

When I added the netlbl_catmap_setlong() function I mistakenly forgot
to mark the associated dummy function as an inline.

Merge branch 'stable-3.17' of git://git.infradead.org/users/pcmoore/selinux

Pull SElinux fixes from Paul Moore:
 "Two small patches to fix a couple of build warnings in SELinux and
  NetLabel.  The patches are obvious enough that I don't think any
  additional explanation is necessary, but it basically boils down to
  the usual: I was stupid, and these patches fix some of the stupid.

  Both patches were posted earlier this week to the SELinux list, and
  that is where they sat as I didn't think there were noteworthy enough
  to go upstream at this point in time, but DaveM would rather see them
  upstream now so who am I to argue.  As the patches are both very
  small"
