drm/radeon: fix a possible null pointer dereference
[ Upstream commit 2c1fe3c480f9e1deefd50d4b18be4a046011ee1f ]
In radeon_tv_get_modes(), the return value of drm_cvt_mode()
is assigned to mode, which will lead to a NULL pointer
dereference on failure of drm_cvt_mode(). Add a check to
avoid null point dereference.
