How do you prevent a userspace process from using the current ucm
module to connect to one of the CMA services on a remote system?  If
you allow that, then the process can use the old simple direct IB CM
interface to put whatever it wants into the REQ private data.

I don't see any handling of the service ID in the ucm or cm code
beyond taking what the consumer passes in and formatting the CM
messages with it.
