Reset TreeId to zero on SMB2 TREE_CONNECT
commit 806a28efe9b78ffae5e2757e1ee924b8e50c08ab upstream.
Currently the cifs module breaks the CIFS specs on reconnect as
described in http://msdn.microsoft.com/en-us/library/cc246529.aspx:
"TreeId (4 bytes): Uniquely identifies the tree connect for the
command. This MUST be 0 for the SMB2 TREE_CONNECT Request."
