Christian Göttsche 477ed6789e selinux: avoid dereference of garbage after mount failure 
commit 37801a36b4 upstream.

In case kern_mount() fails and returns an error pointer return in the
error branch instead of continuing and dereferencing the error pointer.

While on it drop the never read static variable selinuxfs_mount.
