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.

ipv4: Dump stack on attempt to release alive inet socket

We hide the bug, that will make SELinux bomb out. Let's dump the stack
when it happens to have at least a chance to find the cause.
