ipv6: fix restrict IPV6_ADDRFORM operation
Commit b6f6118 ("ipv6: restrict IPV6_ADDRFORM operation") fixed a problem found by syzbot an unfortunate logic error meant that it also broke IPV6_ADDRFORM. Rearrange the checks so that the earlier test is just one of the series of checks made before moving the socket from IPv6 to IPv4.
