staging: r8188eu: the high prio queue is always selected

The high priority queue is always selected, regardless of the number of
out endpoints.

Therefore, haldata->OutEpQueueSel & TX_SELE_HQ is always true. We can
remove the check and use a define instead of the numHQ variable.

This check was the last user of TX_SELE_HQ. Rename haldata->OutEpQueueSel
to haldata->out_ep_extra_queues and store only the queues that are selected
in addition to the high priority queue.
