core: don't shutdown interfaces if they have wowlan enabled

Browse source 
This is to support the S5 case, where usually the NM process is
stopped. If we are stopping and WoWLAN is set for the interface,
we do not deconfigure it and keep the connection alive so we
can receive packages that will potentially wake up the system.

Note that for this work, wpa_supplicant needs to be modified too
so it does not deconfigure the wireless interface either when
stopped. The needed patches for wpa_supplicant can be found in
http://lists.infradead.org/pipermail/hostap/2018-June/038644.html
