Is it necessary to disable modem before powering it down?

I am trying to solve a problem during our system suspend where the disable
modem step takes a long time and it would be quicker to just go straight to
modem power down.

mm-iface-modem.c:handle_set_power_state_auth_ready() checks to make sure
the modem is disabled before allowing it to be powered down.  Is this done
because some modems require it to be in a disabled state before allowing
the power down?
