wpa_supplicant: Fix AP mode frequency initialization

In AP mode the frequency was initialized only after trying to set up the
AP which caused failure. Move AP frequency initialization to the right
place. This allows an AP mode network block without the frequency
parameter to be used with the default channel 11 being selected in that
case.
