[PATCH FOR 2.6.39] gspca - ov519: Fix a regression for ovfx2 webcams

[Jean-Francois Moine <moinejf@free.fr>]

By git commit c42cedbb658b, the bulk transfer size was changed to a lower
value for resolutions != 1600x1200, but the image extraction routine still
worked with the previous value, giving bad truncated images.
