Omit special check for md devices in addUdevDevice().
Omit special check for md devices in addUdevDevice().

If the device appears to be an md device, just call addUdevMDDevice directly.

Use udev_device_get_md_uuid() to get the mduuid of the array, but catch
a key error. This has the same effect as the previous code, but is a bit
more proper, even if more wordy.
