Parav Pandit 65d7a723fd vduse: Tie vduse mgmtdev and its device
[ Upstream commit 0e0348ac3f ]

vduse devices are not backed by any real devices such as PCI. Hence it
doesn't have any parent device linked to it.

Kernel driver model in [1] suggests to avoid an empty device
release callback.

Hence tie the mgmtdevice object's life cycle to an allocate dummy struct
device instead of static one.
