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