Paul Moore 5578de4834 netlabel: fix out-of-bounds memory accesses 
There are two array out-of-bounds memory accesses, one in
cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk().  Both
errors are embarassingly simple, and the fixes are straightforward.

As a FYI for anyone backporting this patch to kernels prior to v4.8,
you'll want to apply the netlbl_bitmap_walk() patch to
cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn't exist before
Linux v4.8.

Fixes: 446fda4f26 ("[NetLabel]: CIPSOv4 engine")
Fixes: 3faa8f982f ("netlabel: Move bitmap manipulation functions to the NetLabel core.")
