From: Chuck Lever <chuck.lever@xxxxxxxxxx>
To handle device removal, svc_rdma_accept() registers an interest in
the underlying device when accepting a connection. However
svc_rdma_free() is not invoked if svc_rdma_accept() fails. There
needs to be a matching "unregister" in that case; otherwise the
device cannot be removed.
Fixes: c4de97f7c454 ("svcrdma: Handle device removal outside of the CM event handler")
