drm/i915/overlay: Prevent divide by zero bugs in scaling
Smatch detected a divide by zero bug in check_overlay_scaling().
drivers/gpu/drm/i915/display/intel_overlay.c:976 check_overlay_scaling()
error: potential divide by zero bug '/ rec->dst_height'.
drivers/gpu/drm/i915/display/intel_overlay.c:980 check_overlay_scaling()
error: potential divide by zero bug '/ rec->dst_width'.
Prevent this by ensuring that the dst height and width are non-zero.
Fixes: 02e792fbaadb ("drm/i915: implement drmmode overlay support v4")
