vxlan: don't allow overwrite of config src addr
When using IPv6 transport and a default dst, a pointer to the configured
source address is passed into the route lookup. If no source address is
configured, then the value is overwritten.
IPv6 route lookup ignores egress ifindex match if the source address is set,
so if egress ifindex match is desired, the source address must be passed
as any. The overwrite breaks this for subsequent lookups.
Avoid this by copying the configured address to an existing stack variable
and pass a pointer to that instead.
Fixes: 272d96a5ab10 ("net: vxlan: lwt: Use source ip address during route lookup.")
