Default Add md arrays to the devicetree with a md# name rather then md/# (#591970)

On Thu, 10 Jun 2010, Hans de Goede wrote:

When an mdraid array with newer metadata versions is created with a name
of md#, like we do, the name returned from devicelibs.mdraid.examine
is in the form of md/#. However if we use that as device name in the
devicetree, then later on when we scan the mdraid array after it was
brought up by handleUdevMDMemberFormat, we will find a md# device as
that is the sysfs name, think it is a different device and add the
device to the tree a second time, this patch fixes this.
