cifs: return DFS root session id in DebugData
Return the DFS root session id in /proc/fs/cifs/DebugData to make it
easier to track which IPC tcon was used to get new DFS referrals for a
specific connection, and aids in debugging.
A simple output of it would be
Sessions:
1) Address: 192.168.1.13 Uses: 1 Capability: 0x300067 Session Status: 1
Security type: RawNTLMSSP SessionId: 0xd80000000009
