[Qemu-devel] [PATCH v2] block: do_commit() does not pass along error messages for all errors |

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'.
Return error using monitor_printf() and strerror(), and covert existing
qerror_report() calls in do_commit() to use monitor_printf().
