Make time_adv use easier for static analyzers

Browse Source 
hapd->time_adv cannot really be NULL if hostapd_update_time_adv()
returns success, but this construction seems to be too difficult
for some static analyzers. While this change is not really needed
in practice, it makes it easier to go through warnings from such
analyzers.
