svcrdma calls svc_xprt_put() in its completion handlers, which currently run in IRQ context. However, svc_xprt_put() is meant to be invoked in process context, not in IRQ context. After the last transport reference is gone, it directly calls a transport release function that expects to run in process context. Change the CQ polling modes to IB_POLL_WORKQUEUE so that svcrdma invokes svc_xprt_put() only in process context. As an added benefit, bottom half-disabled spin locking can be eliminated from I/O paths.
