IB/qib: Issue pre-emptive NAKs on eager buffer overflow
Under congestion resulting in eager buffer overflow attempt to send
pre-emptive NAKs if header queue entries with TID errors are generated
and a valid header is present. This prevents long timeouts and flow
restarts if a trailing set of packets are dropped due to eager
overflows. Pre-emptive NAKs are currently only supported for RDMA
writes.
