[][Fix build error for SDK v5.10]

[Description]
Fix build error for SDK v5.10

The build error is caused by a newly-published
patch on OpenWrt master branch:
https://github.com/openwrt/openwrt/blob/b5f25d
43b7e8eb78bde9659b3ecb651ee5e2f5be/target/linux
/generic/pending-5.10/704-02-net-fix-dev_fill_
forward_path-with-pppoe-bridge.patch

This published change is targeted to apply on
Linux mainline upstream-hnat but not nf-hnat,
so we add it into remove.patch.list to avoid
patch failure.
