The rds module already _has_ cm_id's bound to these devices. So they 
won't "go away" without rds getting an event. The service in question 
was just a quick way to map an ip address to its associated struct 
ib_device. Perhaps this just needs to be a function inside the rds 
module as opposed to something exported from the cma proper...
