media: pvrusb2: correctly return V4L2_PIX_FMT_MPEG in enum_fmt
The pvrusb2 code appears to have a some old workaround code for xawtv that causes a
WARN() due to an unrecognized pixelformat 0 in v4l2_ioctl.c.
Since all other MPEG drivers fill this in correctly, it is a safe assumption that
this particular problem no longer exists.
While I'm at it, clean up the code a bit.
