dshow: prevent division by zero

In the DShow capture module, division by zero is possible in
multiple modulo statements when dealing with granularity values
returned by capture filters.

Change the code so that:
 - if granularity is zero, then width/height/samplingrate must be
   a perfect match with requested settings.
 - if granularity is non zero, then use the old condition tests.

This fixes real crashes reported by VLC users on different forums.

Tested with both a Decklink HD Extreme card and a Decklink HD Pro card.

win32 has a fcntl header but no fcntl function

This reverts commit 9a8efe10.

As the comments says I didn't intend to push it.

This reverts commit f7f50087.
