Log falling back from SAE to WPA2 

I've had connections to a WPA3-Personal only network fail with no log
message from iwd, and eventually figured out to was because the driver
would've required using CMD_EXTERNAL_AUTH. With the added log messages
the reason becomes obvious.

Additionally the fallback may happen even if the user explicitly
configured WPA3 in NetworkManager, I believe a warning is appropriate
there.
