4.9-stable review patch. If anyone has any objections, please let me know.

From: Matthias Kaehlcke <mka@chromium.org>
commit 270e8573145a26de924e2dc644596332d400445b upstream.
The check is already performed in ocontext_read() when the policy is loaded. Removing the array also fixes the following warning when building with clang:
security/selinux/hooks.c:338:20: error: variable 'labeling_behaviors' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
