[PATCH] fb_videomode_to_var: reset virtual screen parameters
fb_videomode_to_var(): reset the virtual screen parameters when converting
from an fb_videomode to an fb_var_screeninfo.
Without this the old virtual screen parameters are kept. Hence you cannot
switch to a video mode with a lower resolution on frame buffer devices that
don't support virtual screens and panning, as values are not supposed to be
rounded down when they don't fit.
I also reordered the assignments to match the order of the individual members.
