rS338611: MFC r338468: Fix "ipfw fwd" to work for incoming IPv4 packets
rS338468: Fix "ipfw fwd" to work for incoming IPv4 packets when ip_tryforward() chooses

Summary

Currently, "ipfw fwd" does not work for incoming IPv4 packets when ip_tryforward chooses fast forwarding path, but it works for IPv6 and for both on old slow path.

This change fixes this adding implementation similar to IPv6 code.

Test Plan

See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=231143 for test plan.
