randr: prevent an unnecessary screen resize with multiple displays

Browse source 
crtc->{x,y} is always 0 when xf86DefaultScreenLimits() is called, so we
calculate too small an area for the initial framebuffer and force a resize
to happen.

This commit fixes the code to use desired{X,Y} instead, which contains the
initial output positions.
