Fix WPA authenticator configuration to not leave uninitialized fields

hostapd_wpa_auth_conf() is called on uninitialized memory and the
conditional blocks in this function may leave some fields into
uninitialized state. This can result in unexpected behavior elsewhere
since some of the variables may be used without matching #ifdef
blocks. Fix this by zeroing the memory.
