Fix ath11k deadlock on WCN6855

[AaronMa]

[Impact]
ath11k is in deadlock when stress reboot or suspend on WCN6855.
sometimes kernel hang.

[Fix]
Fix this by switching from using regulatory_set_wiphy_regd_sync() to
regulatory_set_wiphy_regd(). Now cfg80211 will schedule another workqueue which
handles the locking on it's own. So the ath11k workqueue can simply exit without
taking any locks, avoiding the deadlock.

[Test]
Verified on hardware, stress reboot and suspend 30 times OK.

[Where problems could occur]
It may break ath11k wifi driver.

As an FYI, Kalle is also sending this fix to 6.1-rc with a CC to stable. So this will eventually drop off the Ubuntu kernels as SAUCE.
