xprtrdma: rpcrdma_bc_receive_call() should init rq_private_buf.len
commit 9f74660bcf1e4cca577be99e54bc77b5df62b508 upstream.
Some NFSv4.1 OPEN requests were hanging waiting for the NFS server
to finish recalling delegations. Turns out that each NFSv4.1 CB
request on RDMA gets a GARBAGE_ARGS reply from the Linux client.
Commit 756b9b37cfb2e3dc added a line in bc_svc_process that
overwrites the incoming rq_rcv_buf's length with the value in
rq_private_buf.len. But rpcrdma_bc_receive_call() does not invoke
xprt_complete_bc_request(), thus rq_private_buf.len is not
initialized. svc_process_common() is invoked with a zero-length
RPC message, and fails.
Fixes: 756b9b37cfb2e3dc ('SUNRPC: Fix callback channel')
