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.

SELinux: ipv4: Dump stack on attempt to release alive inet socket

when it happens to have at least a chance to find the cause.
