[ Upstream commit 0e735a4c6137262bcefe45bb52fde7b1f5fc6c4d ]
In 'rtw_wait_firmware_completion()', always wait for both (regular and
wowlan) firmware loading attempts. Otherwise if 'rtw_usb_intf_init()'
has failed in 'rtw_usb_probe()', 'rtw_usb_disconnect()' may issue
'ieee80211_free_hw()' when one of 'rtw_load_firmware_cb()' (usually
the wowlan one) is still in progress, causing UAF detected by KASAN.
Fixes: c8e5695eae99 ("rtw88: load wowlan firmware if wowlan is supported")
