    ath11k: fix AP mode for QCA6390 · 77d7e871

    Commit c134d1f8 ("ath11k: Handle errors if peer creation fails") completely
    broke AP mode on QCA6390:
    
    kernel: [  151.230734] ath11k_pci 0000:06:00.0: failed to create peer after vdev start delay: -22
    wpa_supplicant[2307]: Failed to set beacon parameters
    wpa_supplicant[2307]: Interface initialization failed
    wpa_supplicant[2307]: wlan0: interface state UNINITIALIZED->DISABLED
    wpa_supplicant[2307]: wlan0: AP-DISABLED
    wpa_supplicant[2307]: wlan0: Unable to setup interface.
    wpa_supplicant[2307]: Failed to initialize AP interface
    
    This was because commit c134d1f8 ("ath11k: Handle errors if peer creation
    fails") added error handling for ath11k_peer_create(), which had been failing
    all along but was unnoticed due to the missing error handling. The actual bug
    was introduced already in commit aa44b2f3 ("ath11k: start vdev if a bss peer is
    already created").
    
    ath11k_peer_create() was failing because for AP mode the peer is created
    already earlier op_add_interface() and we should skip creation here, but the
    check for modes was wrong.  Fixing that makes AP mode work again.
    
    This shouldn't affect IPQ8074 nor QCN9074 as they have hw_params.vdev_start_delay disabled.
    
    Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
