staging: greybus: loopback: use gb_loopback_async_wait_all don't spin

Browse source

Currently the greybus-loopback thread logic spins around waiting for
send_count == iteration_max which on real hardware doesn't make a
difference to us but in simulation is excruciatingly slow, anti-social and
bad manners. Use the existing gb_loopback_async_wait_all() function to gate
continuing when the send_count == iteration_max and go to sleep until
there's something worthwhile to-do.
