SVCRDMA: Add check for XPT_CLOSE in svc_rdma_send
SVCRDMA: Add check for XPT_CLOSE in svc_rdma_send
The svcrdma transport can crash if a send is waiting for an
empty SQ slot and the connection is closed due to an asynchronous error.
The crash is caused when svc_rdma_send attempts to send on a deleted
QP.
