drm/panel/panel-tpo-tpg110: fix a possible null pointer dereference
[ Upstream commit f22def5970c423ea7f87d5247bd0ef91416b0658 ]
In tpg110_get_modes(), 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.
