selinux: Fix regression for Xorg

Commit 6f5317e730505d5cbc851c435a2dfe3d5a21d343 introduced a bug in the
handling of userspace object classes that is causing breakage for Xorg
when XSELinux is enabled.  Fix the bug by changing map_class() to return
SECCLASS_NULL when the class cannot be mapped to a kernel object class.
