bnxt_en: ethtool: Improve wildcard l4proto on ip4/ip6 ntuple rules

This patchset improves wildcarding over l4proto on ip4 and ip6 nutple
rules. Previous support required setting l4proto explicitly to 0xFF if
you wanted wildcard, which ethtool (naturally) did not do. For example,
this command would fail with -EOPNOSUPP:

    ethtool -N eth0 flow-type ip6 dst-ip $IP6 context 1

After this patchset, only TCP, UDP, ICMP, and unset will be supported
for l4proto.
