A queue entry lookup currently looks like this:
ipq_find_dequeue_entry -> __ipq_find_dequeue_entry ->
__ipq_find_entry -> cmpfn -> id_cmp
Use simple open-coded list walking and kill the cmpfn for
ipq_find_dequeue_entry. Instead add it to ipq_flush (after
similar cleanups) and use ipq_flush for both complete flushes
and flushing entries related to a device.
