xf86Cursor: Fix xf86_crtc_rotate_coord using width/height wrongly
xf86_crtc_rotate_coord should be the exact inverse operation of xf86_crtc_rotate_coord_back, but when calculating x / y for 90 / 270 degrees rotation it was using height to calculate x / width to calculate y, instead of the otherway around. This was likely not noticed before since xf86_crtc_rotate_coord until now was only used with cursor_info->MaxWidth and cursor_info->MaxHeight, which are usally the same.
