VSMB direct map requires support for querying FileIdInfo from the backing volume. There is a bug in certain Windows versions where instead of falling back to non-direct map when FileIdInfo is not supported, VSMB instead causes errors whenever files on the share are accessed. To work around this until the issue is fixed, we will query FileIdInfo ourselves when setting up a VSMB share, and force disable direct map if the query fails.
