Gong Yuanjun c17d09488c drm/radeon: fix a possible null pointer dereference
[ Upstream commit a2b28708b6 ]

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.
