V4L/DVB (7938): pvrusb2: Increase enforced encoder wait delay to improve reliability

Browse source 
The driver enforces a "quiet period" on the encoder in certain
situations before attempting to operate it.  This seems to help avoid
video encoding errors / corruption.  The quiet period was 50msec, but
through experimentation it has been observed to improve further if the
interval is increased to 100msec.
