selinux: add a ugly workaround to bail early when selinux tries to free a socket that is still in use and it ends in a Kernel panic. These lines are from opensource.samsung.com. While this will most likely put a bandaid over this Kernel panic it does not fix the bug so it might occur somewhere else if the same conditions are met but since I have only seen panics from this hook then we may as well sleep in peace.
