drm/amd/display: Fix KUnit MST warnings
[WHY]
The MST add-connector fixture registers an unmanaged master connector
but does not clean it up before its KUnit-owned storage is released.
[HOW]
Register a KUnit action after successful connector initialization to
run drm_connector_cleanup before freeing the master connector.
