PATCH: Recognize /sys/block/dm-X as a devicemapper dev (and thus call handledm)

[Hans de Goede <hdegoede redhat com>]

One of my last patches moved the checking for Volgroups to handledm, however
when the root device is specified in fstab as /dev/VolGroup00/Volume00,
handledm never gets called, as neither /dev/VolGroup00/Volume00 nor
/sys/block/dm-X are recognized as being dm by findstoragedriver ()

This patch fixes findstoragedriver () to recognize atleast /sys/block/dm-X
as dm.

p.s.

Why are we still calling findstoragedriver twice in cases like this ???
