[PATCH] wifi: ath11k: don't report a regulatory event skipped in recovery

[Christopher Griffin via B4 Relay]

From: Christopher Griffin <christophergriffin05@xxxxxxxxx>

During firmware recovery, ath11k_reg_handle_chan_list() deliberately
ignores the regulatory event when the radio already has its default
regd, but it does so by returning -EINVAL, so every recovery logs a
failure:

  ath11k_pci 0001:01:00.0: failed to process regulatory info -22

Before commit 7004bdceef60 ("wifi: ath11k: store cur_regulatory_info
for each radio") moved this code out of ath11k_reg_chan_list_event(),
the skip freed the event's rules and returned 0.

Do that again for the event (IEEE80211_REG_UNSET_AP), the same way as
the skip of an unchanged default regd below it. The calls from mac.c
pass the stored rules with a 6 GHz power type, never
IEEE80211_REG_UNSET_AP; they keep getting -EINVAL during recovery, and
the stored rules are left alone.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.r4-00683-QCAHKSWPL_SILICONZ-1

Fixes: 7004bdceef60 ("wifi: ath11k: store cur_regulatory_info for each radio")
