When using "pwcview -s svga -f 20 -k"
* When pwcview sets the resolution to use, the V4L layer will reply with the
actual resolution set. As close as possible to what pwcview requested.
Fix a bug in main() that it uses the wrong size value, the resolution pwcview
set instead of the size the V4L layer returned.
