There was mistaken in
649178c0493e ("mt76: mt7921e: fix possible probe failure after reboot")
that caused WiFi reset cannot work well as the reported issue
"PROBLEM: [Stable v5.15.42+] [mt7921] Wake after suspend locks up system
when mt7921-driver is used on a Lenovo ThinkPad E15 G3"
in http://lists.infradead.org/pipermail/linux-mediatek/2022-June/042668.html
So we need to revert the patch first. Will be applied again later.
