Subject: svcrdma: Drop connection after an RDMA Read error
From: Chuck Lever <chuck.lever@xxxxxxxxxx>
commit 197115ebf358cb440c73e868b2a0a5ef728decc6 upstream.
When an RPC Call message cannot be pulled from the client, that
is a message loss, by definition. Close the connection to trigger
the client to resend.
