svcrdma: Avoid Send Queue overflow
Sanity case: Catch the case where more Work Requests are being
posted to the Send Queue than there are Send Queue Entries.
This might happen if a client sends a chunk with more segments than
there are SQEs for the transport. The server can't send that reply,
so the transport will deadlock unless the client drops the RPC.
