V4L/DVB (6707): pvrusb2: Remove use of volatile in pipeline control state machine 

pvrusb2: Eliminate use of volatile in pipeline control state
variables.  These were all cases of paranoia; upon further review the
overall mechanism employed here should not require use of volatile.
This had originally been done out of paranoia, and I have since been
convinced that the paranoia is not required.
