Revert "mt76: mt7921: Fix the error handling path of mt7921_pci_probe()"

This reverts commit 2fc516a73ed270b2739cbe4ecc19c743b3730613 that is the
commit 043ee44d54486eef5b234982f58f52f4268624af upstream.

Because there was mistake in
'5c03980e30f6 ("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
'5c03980e30f6 ("mt76: mt7921e: fix possible probe failure after reboot")'
and will be applied back later after fixing.
