Revert "drm: hide unregistered connectors from GETCONNECTOR IOCTL"
This reverts commit 981f09295687f856d5345e19c7084aca481c1395.
It turns out this causes logically active but disconnected DP MST
connectors to disappear from the KMS resources list, and Mutter
then assumes the connector is already disabled. Later on Mutter tries
to re-use the same CRTC but fails since on the kernel side it's still
tied to the disconnected DP MST connector.
