[PATCH] selinux: Mark array 'labeling_behaviors' as __maybe_unused

[Matthias Kaehlcke]

The array is only referenced in an ARRAY_SIZE() statement. Adding the
attribute 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]
