cirrus_vga: fix division by 0 for color expansion rop
Commit d85d0d3883f5a567fa2969a0396e42e0a662b3fa introduces a regression
with Windows ME that leads to a division by 0 and a crash.
It uses the color expansion rop with the source pitch set to 0. This is
something allowed, as the manual explicitely says "When the source of
color-expand data is display memory, the source pitch is ignored.".
This patch fixes this regression by computing sx, sy and others
variables only if they are going to be used later, that is for a plain
copy ROP. It basically consists in moving code.
