selinux: Fix regression for Xorg
Stephen Smalley authored
Commit 6f5317e7

 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.
