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.
