Sunil Dutt 62657365f8 Add a configuration to disconnect on deinit if WoWLAN is enabled
Commit 02c21c02d0 ("wpa_supplicant: Do not disconnect on deinit if
WoWLAN is enabled") prevents the disconnection on deinit if the driver
indicates that WoWLAN is enabled. This is not the expected behavior in
some earlier use cases where the wpa_supplicant process is left running
when going to sleep and killing of the wpa_supplicant process is used
only when there is an expectation of Wi-Fi connection being disabled.

To support the use cases which require the WLAN to disconnect on deinit
even if WoWLAN is enabled, introduce a configuration parameter
wowlan_disconnect_on_deinit. This is set to 0 by default thereby not
impacting the functionality in the above mentioned commit. Setting it to
1 restores the old behavior before the commit identified above.
