[Joe Perches <joe@perches.com>]

Return a negative error value like the rest
of the entries in this function.

Maybe this should be stable, it goes back to
commit b77a493b1dc8 ("SELinux: standardize return code
handling in selinuxfs.c") back in Nov 2010, but it's
guarded by a #ifdef CONFIG_SECURITY_SELINUX_DEVELOP
so it probably doesn't matter much.
