drm: add proper return value for drm_mode_crtc_set_gamma_size 

drm_mode_crtc_set_gamma_size returns boolean true for success
and false for failure. This is not very kernel conform, so
change it to return 0 for success and a propert error code
otherwise. Noone checks the return value, so no users have to
be fixed.
