Sagi Grimberg fd0823f405 nvme-tcp: fix a NULL deref when receiving a 0-length r2t PDU 
When the controller sends us a 0-length r2t PDU we should not attempt to
try to set up a h2cdata PDU but rather conclude that this is a buggy
controller (forward progress is not possible) and simply fail it
immediately.
