Subject: viafb: use proper register for colour when doing fill ops
From: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

The colour was written to a wrong register for fillrect operations.  This
sometimes caused empty console space (for example after 'clear') to have a
different colour than desired.  Fix this by writing to the correct
register.

Many thanks to Daniel Drake and Jon Nettleton for pointing out this issue
and pointing me in the right direction for the fix.
