drm/bridge: cdns-mhdp8546: Improve error reporting in remove callback
Replace the generic error message issued by the driver core when the remove
callback returns non-zero ("remove callback returned a non-zero value. This
will be ignored.") by a message that tells the actual problem.
Also simplify a bit by checking the return value of wait_event_timeout a
bit later.
