[ipv6] Avoid potentially copying from a NULL pointer in ipv6_tx()
If ipv6_tx() is called with a non-NULL network device, a NULL or
unspecified source address, and a destination address which does not
match any routing table entry, then it will attempt to copy the source
address from a NULL pointer.
I don't think that there is currently any code path which could
trigger this behaviour, but we should probably ensure that it can
never happen.
