[PATCH] wifi: ath12k: use link specific bss_conf as well in ath12k_mac_vif_cache_flush()

[Baochen Qiang]

Commit 3952657848c0 ("wifi: ath12k: Use mac80211 vif's link_conf instead of
bss_conf") aims at, where applicable, replacing all usage of vif's bss_conf
with link specific bss_conff, but missed one instance in
ath12k_mac_vif_cache_flush(). This results in wrong configurations passed
to ath12k_mac_bss_info_changed() when the link in question is not the default
link.

Change to use the link specific bss_conf to fix this issue.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
