qcacld-3.0: Host sends VDEV_DELETE cmd to fw before stop_bss
When stop_ap command comes from userspace, __wlan_hdd_cfg80211_stop_ap
calls sap_fsm to change the states of SAP from started to disconnect.
In order to change SAP states, __wlan_hdd_cfg80211_stop_ap sends
WMI_VDEV_STOP_CMDID followed by WMI_VDEV_DOWN_CMDID and
WMI_VDEV_DELETE_CMDID to fw. After the successful change in state of
SAP machine, driver invokes an HDD callback, hdd_hostapd_sap_event_cb
for cleanup and subsequently invokes hdd_softap_stop_bss to reclaim all
resources. This API sends IPA_OFFLOAD_ENABLE_DISABLE cmd to fw for the
VDEV on which SAP started. Which results assert in firmware as host
sends HDD IPA event for the VDEV which is already deleted while changing
the state of SAP.
Fix is to send HDD_IPA_AP_DISCONNECT IPA events before stop BSS.
