Subject: [PATCH] smbd: Fix snapshot query on shares with DFS enabled

When DFS is enabled (host msdfs = yes and msdfs root = yes), then SMB
clients send create requests in the format \hostname\service\path.
Putting the GMT tag as first element breaks the DFS parsing and results
in OBJECT_NOT_FOUND for snapshotted files.  Fix this by appending the
GMT tag to the end of the path.
