Change log level of wpa_supplicant, to prevent unnecessary log-file entries

[schmo90]

if the device is connected to older wlan-aps the log file is overflowing with this error message:

wpa_supplicant[2047]: RRM: Ignoring radio measurement request: Not RRM network

to disable this warning it is necessary to change log level to warning:
dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1 /fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set string:fi.w1.wpa_supplicant1 string:DebugLevel variant:string:warning

connect to wifi
check log file with
journalctrl -f
