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. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
