Subject: [PATCH] mesh: properly handle sae_password

The recently introduced sae_password parameter is only handled properly
in wpa_supplicant/sme.c while wpa_supplicant/mesh.c assumed that
ssid->passphrase exclusively holds the secret.
Import the logic from sme.c to mesh.c to allow having only sae_password
set which otherwise throws this error:
AP-ENABLED
mesh: Passphrase for SAE not configured
Init RSN failed. Deinit mesh...
wlan1: interface state ENABLED->DISABLED
AP-DISABLED
Segmentation fault
