V4L/DVB: ivtv: Avoid hard system lock on decoder output mode change

Browse source

Changing the decoder video standard just prior to, or during, the output of
the lower field may result in a hard system lock. To avoid this, try to ensure
the firmware call occurs only during the first 100 lines of the top field.

(Minor comment addition and a line break added Andy Walls <awalls@radix.net>.)
