Describe the bug When using linux-wifi-hotspot on a WiFi adapter that's already used as a client (like with wpa_supplicant), the linux-wifi-hotspot script hangs.

To Reproduce

  1. Use wpa_supplicant to connect to a wireless network with adapter wlan0.
  2. Create a WiFi hotspot on wlan0: 
    create_ap wlan0 my-wan-iface myhotspot mypasswd

    Stdout:

    ...
Sharing Internet using method: nat
hostapd command-line interface: hostapd_cli -p /tmp/create_ap.wlan0.conf.28LbRTnt/hostapd_ctrl
ap0: interface state UNINITIALIZED->ENABLED
ap0: AP-ENABLED 
ap0: INTERFACE-DISABLED

    At this point, the script hangs.

Expected behavior An error message that points to the cause of the error instead of the unspecific msg ap0: INTERFACE-DISABLED.

Environment linux-wifi-hotspot 4.6.0 Adapter: Intel Corporation Wi-Fi 6 AX200 (kernel module iwlwifi)
