V4L/DVB (7701): pvrusb2: Centralize handling of simple FX2 commands
Numerous places in the driver need to issue simple commands to the FX2
microcontroller (e.g. only 1 or 2 bytes, no reply needed). Previously
each place that did this, had to take lock, set up a central buffer,
and call the function to perform the handshake. This change puts
these steps into a single spot. This also has the effect of removing
the need to mess with the control lock from numerous places in the
code.
