[][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/87b6e
10c71203d2dedd8a56dea91390dac00c525#diff-89de1a
88babc21161914d52b52f12439e7b3e0b4c08331efb54d2
1444eb9a76a

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