[PATCH] wpa_supplicant: send event to all interfaces

[Janusz Dziedzic]

In case we don't have ifidx and wdev_id pass
such event to all interfaces and bss.
Before we send event only to first interface and
in case we are using p2p-dev we send event only
to this one iface:

p2p-dev-wlan0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD

Because of that we fail hwsim test cases eg. ibss_5ghz,
while we never get CTRL-EVENT-REGDOM-CHANGE on wlan0.

I also remove for_each() from wpa_supplicant_update_channel_list()
while this function will be called now for each interface.
So, seems this for_each() was a workaround for a real issue.

Now, seems we pass test where we wait for REGDOM event
