x86, smap: Don't enable SMAP if CONFIG_X86_SMAP is disabled
commit 03bbd596ac04fef47ce93a730b8f086d797c3021 upstream.
If SMAP support is not compiled into the kernel, don't enable SMAP in
CR4 -- in fact, we should clear it, because the kernel doesn't contain
the proper STAC/CLAC instructions for SMAP support.
