Add sanity checks for cport_quiesce and cport_clear before invoking the

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.

The probe function is not marked __init, but some other functions
are. This leads to a warning on older compilers (e.g. gcc-4.3),
and can cause executing freed memory when built with those
compilers:
WARNING: drivers/staging/emxx_udc/emxx_udc.o(.text+0x2d78): Section mismatch in reference from the function nbu2ss_drv_probe() to the function .init.text:nbu2ss_drv_contest_init()
