[ Upstream commit ed7e818a7b501012038d6bc6fedadaf7375a380a ]
For AP mode, the peer is created earlier in ath12k_mac_op_add_interface() but ath12k_mac_op_assign_vif_chanctx() will try to create peer again. Then an error will return which makes AP mode startup fail.
Kernel log:
[ 5017.665006] ath12k_pci 0000:04:00.0: failed to create peer after vdev start delay: -22
wpa_supplicant log:
Failed to set beacon parameters Interface initialization failed wls1: interface state UNINITIALIZED->DISABLED wls1: AP-DISABLED wls1: Unable to setup interface. Failed to initialize AP interface wls1: interface state DISABLED->DISABLED wls1: AP-DISABLED
So fix this check and enable AP mode for WCN7850, as now AP mode works normally.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
