V4L/DVB (9800): cx18: Eliminate q_io from stream buffer handling
Eliminate q_io from stream buffer handling in anticipation of upcoming
changes in buffer handling. q_io was a holdover from ivtv and it's function
in cx18 was trivial and not necessary. We just push things back onto the
front of q_full now, instead of maintaining a 1 buffer q_io queue.
