wifi: ath12k: fix and enable AP mode for WCN7850

[ 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
