[PATCH v1 4/7] xen_pvdev: Do not assume Dom0 when creating a directrory

[Volodymyr Babchuk]

From: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com>

Instead of forcing the owner to domid 0, use XS_PRESERVE_OWNER to save
the previous owner of the directory.

Note that for other than Dom0 domain (non toolstack domain) the
"driver_domain" property should be set in domain config file for the
toolstack to create required directories in advance.
