Christian Helmuth 0b247f81f8 wifi: disable scheduled scanning on Intel MVM cards
On MVM only the initial scanning of APs works. If wpa_supplicant changes
from triggered scans to the scheduled-scanning hardware feature no
further scan results are reported. Therefore, we disable the
scheduled-scanning hardware feature until the issue is fixed.
