[][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/commit/e316
6643fbc9f3cf67948c660a76b5cc60bf0ef8

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.
