packets: Re-calculate IPv6 checksum only for first frag upon modify.
In case of modifying an IPv6 packet src/dst address the L4 checksum
should be recalculated only for the first frag. Currently it's done
for all frags, leading to incorrect reassembled packet checksum.
Fix it by adding a new flag to recalculate the checksum only for the
first frag.
Fixes: bc7a5acdff08 ("datapath: add ipv6 'set' action")
