[PATCH] bridge: fix forwarding of IPv6

[Stephen Hemminger <shemminger@xxxxxxxxxx>]

The commit 6b1e960fdbd75dcd9bcc3ba5ff8898ff1ad30b6e
    bridge: Reset IPCB when entering IP stack on NF_FORWARD
broke forwarding of IPV6 packets in bridge because it would
call bp_parse_ip_options with an IPV6 packet.
