[PATCH] selinuxfs cleanups: sel_fill_super exit path
Unify the error path of sel_fill_super() so that all errors pass through the
same point and generate an error message. Also, removes a spurious dput() in
the error path which breaks the refcounting for the filesystem
(litter_kill_super() will correctly clean things up itself on error).
