mwifiex: reduce CPU usage by tracking highest_queued_prio
This patch adds highest_queued_prio to track priority of packets as
they are enqueued so that mwifiex_wmm_get_highest_priolist_ptr()
starts checking at the first level where we have packets, instead of
the highest. The function also lowers priority value to the level
where first packet is found.
