Jason A. Donenfeld 320f2dce19 hwrng: core - let sleep be interrupted when unregistering hwrng 
commit 36cb649442 upstream.

There are two deadlock scenarios that need addressing, which cause
problems when the computer goes to sleep, the interface is set down, and
hwrng_unregister() is called. When the deadlock is hit, sleep is delayed
for tens of seconds, causing it to fail. These scenarios are:

1) The hwrng kthread can't be stopped while it's sleeping, because it
   uses msleep_interruptible() which does not react to kthread_stop.

2) A normal user thread can't be interrupted by hwrng_unregister() while
   it's sleeping, because hwrng_unregister() is called from elsewhere.

We solve both issues by add a completion object called dying that
fulfils waiters once we have started the process in hwrng_unregister.

At the same time, we should cleanup a common and useless dmesg splat
in the same area.
