FROMLIST: wifi: ath11k: Fix failure to connect to a 6 GHz AP

STA fails to connect to a 6 GHz AP with the following errors:
 ath11k_pci 0000:01:00.0: failed to handle chan list with power type 1
 wlp1s0: deauthenticating from c8:a3:e8:dd:41:e3 by local choice (Reason: 3=DEAUTH_LEAVING)

ath11k_reg_handle_chan_list() treats the update as redundant and
returns -EINVAL. That causes the connection attempt to fail.

Avoid unnecessary validation during association. Apply the regulatory
redundant check only when the power type is IEEE80211_REG_UNSET_AP,
which only occurs during core initialization.

Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.41
