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: 196cd5d3758c ("drm: s/drm_crtc_get_hv_timings/drm_mode_get_hv_timings/")
