Handle hostapd_for_each_interface() at the process termination

Browse source 
Clean struct hapd_interfaces pointers and interface count during
deinitialization at the end of theh ostapd process termination so that a
call to hostapd_for_each_interface() after this does not end up
dereferencing freed memory. Such cases do not exist before this commit,
but can be added after this, e.g., for DPP needs.
