xvmc: Don't copy on xvmc surface in PutImage
As xvmc rendering result has already been in fb, we shouldn't
do extra copy on it. Although special care is required for i915
xvmc surface pitch alignment, which must be at least 1KB aligned.
So video display function should take it into acount instead of
always setting Y pitch to be double of U/V pitch.
