I don't have a good solution yet for calls like ib_cma_get_device(). Yet
another possibility is to have it return a device pointer in a callback.
Then it can synchronize with device removal internally.
What if ib_cma_get_device() will return client data for the device and
we let the ULP to figure out whether the data is still valid in the way
most suitable for the ULP?
While I think that returning the client data would be useful, I don't think that
this really helps the ULP any. It seems likely that a client would free their
client data upon removal of the associated device. So they can't trust this
pointer any more than the device pointer.
