IB/hfi1: Add additional checks when handling TID RDMA READ RESP packet
In a congested fabric with adaptive routing enabled, traces show that
packets could be delivered out of order, which could cause incorrect
processing of stale packets. For stale TID RDMA READ RESP packets that
cause KDETH EFLAGS errors, this patch adds additional checks before
processing the packets.
Fixes: 9905bf06e890 ("IB/hfi1: Add functions to receive TID RDMA READ response")
