* Shut down CMRC connection gracefully

*
* The Infiniband data structures are not reference-counted or
* guarded. It is therefore unsafe to shut them down while we may be
* in the middle of a callback from the Infiniband stack (e.g. in a
* receive completion handler).
*
* This shutdown process will run some time after the call to
* ib_cmrc_close(), after control has returned out of the Infiniband
* core, and will shut down the Infiniband interfaces cleanly.
*
* The shutdown process holds an implicit reference on the CMRC
* connection, ensuring that the structure is not freed before the
* shutdown process has run.
