net: fix dev_fill_forward_path with pppoe + bridge
When calling dev_fill_forward_path on a pppoe device, the provided destination
address is invalid. In order for the bridge fdb lookup to succeed, the pppoe
code needs to update ctx->daddr to the correct value.
Fix this by storing the address inside struct net_device_path_ctx
Fixes: f6efc675c9dd ("net: ppp: resolve forwarding path for bridge pppoe devices")
