Merge branch 'eth-fbnic-cleanup-and-add-a-few-stats'

Jakub Kicinski says:

====================
eth: fbnic: cleanup and add a few stats

Cleanup trival problems with fbnic and add the PCIe and RPC (Rx parser)
stats.

All stats are read under rtnl_lock for now, so the code is pretty
trivial. We'll need to add more locking when we start gathering
drops used by .ndo_get_stats64.
