This reverts commit 663457f421d41e9d2fcb1e84baf43d1433f80c08 that is the commit 44c4237cf3436bda2b185ff728123651ad133f69 upstream.
Because there was mistake 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" described in http://lists.infradead.org/pipermail/linux-mediatek/2022-June/042668.html So we need to revert the patch first to avoid the conflict of reverting '649178c0493e ("mt76: mt7921e: fix possible probe failure after reboot")' and will be applied back later after fixing.
