datapath/actions: Mark recalculate_csum as likely in set_ipv6_addr().
The ‘recalculate_csum’ is almost always ‘true’. It is false only if
the ipv6 nexthdr is an extension header, and a routing header is
found. For the majority of ipv6 packets this would not be the case,
so this can be marked as 'likely'.
