[ Upstream commit 11d963d44c77261d6a948f3745bbd678eef4b83b ]
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.
