msm: mdss: fix sw calculation of interlace x offset 



Interlacing is handled in software by changing the original height to
half which would become the width after rotation. In cases of 90 degree
rotation the height becomes the displayed width so in that case the
source x offset needs to be updated to half of intended similar to
source width.
