drm/amd/display: fix memleak in aconnector->timing_requested
[Why] when amdgpu_dm_update_connector_after_detect is called two times successively with valid sink, memory allocated of aconnector->timing_requested for the first call is not free. this causes memeleak. [How] allocate memory only when aconnector->timing_requested is null.
