sfc: offload foreign RHS rules without an encap match
Normally, if a TC filter on a tunnel netdev does not match on any
encap fields, we decline to offload it, as it cannot meet our
requirement for a <sip,dip,dport> tuple for the encap match.
However, if the rule has a nonzero chain_index, then for a packet to
reach the rule, it must already have matched a LHS rule which will
have included an encap match and determined the tunnel type, so in
that case we can offload the right-hand-side rule.
