xf86: set status to connected for monitors enabled in conf

If the user sets Option "Enable" "TRUE" for a monitor, the X server will connect the connector a crtc but tell the user it is disconnected.

However the user in this case is mutter, when it gets it's view of the output configuration it sees the output is disconnected and never sets it up again, which seems like the right thing to do.

If we let the user enable a monitor, lets just set it as always connected.
