mus: Send display-id to client only for the root windows.

Child windows are always in the same display as their parent windows, so
it doesn't make sense to always send the display-id for each window
created.  Instead, notify the client about the display each root-window
is on, and have the client be responsible for tracking that for each
child window afterwards.
