wwan: set modem to low power state when disabling

Browse source 
When WWAN airplane mode is enabled, set modems to low power state to
ensure they are in airplane mode if either (a) the machine does not
have an rfkill switch, or (b) the modem is not tied to any rfkill
switch (eg, external USB/SDIO/etc).
