CIFS: Reconnect durable handles for SMB2
On reconnects, we need to reopen file and then obtain all byte-range locks held by the client. SMB2 protocol provides feature to make this process atomic by reconnecting to the same file handle with all it's byte-range locks. This patch adds this capability for SMB2 shares.
