[0/3] drm/msm: dsi: Properly handle disconnected secondary dsi block

Message

The configuration where dsi0 is connected and dsi1 is disconnected
doesn't work currently. When dsi1 fails, it paves the reference to dsi0
in dsi_manager, which causes mass carnage. This set ensures that we
clean up the correct dsi device, and that we fail gracefully if a device
is not connected to anything.
