sfc: optional logging of TC offload errors
TC offload support will involve complex limitations on what matches and
actions a rule can do, in some cases potentially depending on rules
already offloaded. So add an ethtool private flag "log-tc-errors" which
controls reporting the reasons for un-offloadable TC rules at NETIF_INFO.
