IB/hfi1: Show fault stats in both TX and RX directions
The routine which shows the fault stats checks the counters
to determine whether to show any stats based on the number of
transmitted pkts/bytes for a particular opcode.
Unfortunately, it only checked the receive counters. As a result,
if any packet faults have happened for packets egressing the HFI,
those stats would not be shown.
In order to fix this, the routine is amended to also check the
TX counters. With this change the pkt/byte counts are the sum of
both TX and RX counts for the opcode.
Fixes: 1b311f8931cf ("IB/hfi1: Add tx_opcode_stats like the opcode_stats")
