Subject: [PATCH] fdasd: skip partition check and BLKRRPART ioctl for emulated
 devices

If 'fdasd -f' is called we cannot rely on the partition detection
via a simple check of the minor number, so the check should be
suppressed.
Similarly, not every emulated device supports the BLKRRPART ioctl,
so we should be suppressing the error message for these devices, too.
