Revert "staging: vc04_services: vchiq_core: Stop kthreads on shutdown"

Browse source

This reverts commit d9c60badcc.

It has been reported that stopping kthreads corrupts the VC04 firmware
and creates issues at boot time [1].

A fix-up version of this patch
bac670144384 ("staging: vc04_services: Stop kthreads on .remove") [2]
was also attempted but it also doesn't properly fix the TODO
(i.e. clean module unload) and similar errors were observed when
stopping these khthreads on RaspberryPi 3.

Hence, revert the entire patch for now since it is not very clear why
stopping the kthreads breaks the firmware.
