net: wirelss: bcmdhd fix the corner case of PCIe linkdown

1) [Issue 17755061] Wi-Fi stuck in Off position
with new log, we missed the one case for NON-IOCTL.
Sometimes we have issue for deleting flow ring.
2) For failure of WLAN-on, we don't set g_wifi_on to TRUE.
So, we don't do anything to clear resource even through framework
will call wl_android_wifi_off
