hostapd: Clear keys configured when hostapd reloads configuration

Data path is broken when hostapd reloads its configuration
disabling the security which was previously enabled (WEP/WPA),
using kill -1, as old keys were not cleared.

The patch clears the keys configured when hostapd reloads
its configuration.
