pvrusb2: Fix tuning calculation when in radio mode
From: Mike Isely <isely@pobox.com>
Frequency units in V4L2 are apparently different when in radio mode
compared to tv mode. Why? Who knows. This change adapts the driver
appropriately - so that internally we always only deal in Hz and don't
have to muck with craziness like this.
