The non-live bdrv_commit() function may return one of the following errors: -ENOTSUP, -EBUSY, -EACCES, -EIO. The only error that is checked in the HMP handler is -EBUSY, so the monitor command 'commit' silently fails for all error cases other than 'Device is in use'. Report error using monitor_printf() and strerror(), and convert existing qerror_report() calls in do_commit() to monitor_printf().
