[usb-moded-qt5] Ignore reply to com.meego.usb_moded.set_mode() method…

… call. JB#42756

The set_mode() method call merely initiates mode transition, and a separate
signal will be broadcast when/if it finishes.

Ignore set_mode() reply value, but leave the pending call handler in place
as it still has use from debugging point of view.
