drisw: Copy entire buffer ignoring damage regions

Browse source 
swapping buffers with damage is supposed to swap the entire buffer
and only pass the damage region as a hint to compositor as to what
updated. This change forces drisw to copy the entire buffer as there
is no method right now to check what was updated.
