net: airoha: add RCU lock around dev_fill_forward_path

Browse Source 
Since 0417adf367 ("ppp: fix race conditions in ppp_fill_forward_path")
dev_fill_forward_path() should be called with RCU read lock held. This
fix was applied to net, while the Airoha flowtable commit was applied to
net-next, so it hadn't been an issue until net was merged into net-next.

Fixes: a8bdd935d1 ("net: airoha: Add wlan flowtable TX offload")
