Based on the upstream feedback, driver should not use any
defensive programming strategy by checking for NULL pointers
and other conditional checks unnecessarily in the code flow
to fall back, instead fail and fix the bug in a proper way.
As the control queue is freed and deleted from the list after the
idpf_ctlq_shutdown call, there is no need to have the ring_size
check in idpf_ctlq_shutdown.
