[LIU]: QUEUE_FLAG_STANDBY bit MUST be cleared here, as it is the only place

the ploop device recovers from standby mode. In our use case, once a ploop
device enters standby

without destroying
the device, which is why the bit is clear in 'repalce_delta' in vz7.
static int ploop_replace_delta(struct ploop_device * plo, unsigned long arg)
{
...
if (plo->maintenance_type != PLOOP_MNTN_OFF)
return -EBUSY;
...
}
If that is used to clear the flag then how is the case when the error
occurs while in maintenace handled? I think we should address this too.
