[PATCH 02/10] hostapd: Clear location configuration when it is reset

[Andrei Otcheretianski]

From: Ilan Peer <ilan.peer at intel.com>

In case that LCI or location civic configuration is cleared,
free the buffer holding the corresponding information to avoid
cases that the information is considered as valid/useful.
