drm: Silence the compiler for drm_mode_get_hv_timings() 



Since moving drm_crtc_get_hv_timings() into drm_modes.c, the compiler
has been able to get smarter and spots that drm_mode_copy() is trying to
preserve garbage from the stack.

Fixes: 196cd5d3 ("drm: s/drm_crtc_get_hv_timings/drm_mode_get_hv_timings/")
