nvme-rdma: use ib_client API to detect device removal
Change nvme-rdma to use the IB Client API to detect device removal.
This has the wonderful benefit of being able to blow away all the
ib/rdma_cm resources for the device being removed. No craziness about
not destroying the cm_id handling the event. No deadlocks due to broken
iw_cm/rdma_cm/iwarp dependencies. And no need to have a bound cm_id
around during controller recovery/reconnect to catch device removal
events.
We don't use the device_add aspect of the ib_client service since we only
want to create resources for an IB device if we have a target utilizing
that device.
