wifi: mt76: mt7921s: fix potential hung tasks during chip recovery

2024-06-27T11:52:14Z

[ Upstream commit ecf0b2b8a37c8464186620bef37812a117ff6366 ] During chip recovery (e.g. chip reset), there is a possible situation that kernel worker reset_work is holding the lock and waiting for kernel thread stat_worker to be parked, while stat_worker is waiting for the release of the same lock. It causes a deadlock resulting in the dumping of hung tasks messages and possible rebooting of the device. This patch prevents the execution of stat_worker during the chip recovery.
