ipv6: Fix potential uninit-value access in __ip6_make_skb()
As it was done in commit fc1092f51567 ("ipv4: Fix uninit-value access in
__ip_make_skb()") for IPv4, check FLOWI_FLAG_KNOWN_NH on fl6->flowi6_flags
instead of testing HDRINCL on the socket to avoid a race condition which
causes uninit-value access.
Fixes: ea30388baebc ("ipv6: Fix an uninit variable access bug in __ip6_make_skb()")
