drm/radeon: fix a possible null pointer dereference
[ Upstream commit a2b28708b645c5632dc93669ab06e97874c8244f ]
In radeon_fp_native_mode(), the return value of drm_mode_duplicate()
is assigned to mode, which will lead to a NULL pointer dereference
on failure of drm_mode_duplicate(). Add a check to avoid npd.
The failure status of drm_cvt_mode() on the other path is checked too.
