Trond Myklebust f39c1bfb5a SUNRPC: Fix a UDP transport regression ... Commit 43cedbf0e8 (SUNRPC: Ensure that we grab the XPRT_LOCK before calling xprt_alloc_slot) is causing hangs in the case of NFS over UDP mounts. Since neither the UDP or the RDMA transport mechanism use dynamic slot allocation, we can skip grabbing the socket lock for those transports. Add a new rpc_xprt_op to allow switching between the TCP and UDP/RDMA case. Note that the NFSv4.1 back channel assigns the slot directly through rpc_run_bc_task, so we can ignore that case.
