Pull smb server and smbdirect updates from Steve French:

- Fix tcp connection leak

- Fix potential use after free when freeing multichannel

- Fix locking problem in showing channel list

- Locking improvement for tree connection

- Fix infinite loop when signing errors

- Add /proc interface for monitoring server state

- Fixes to avoid mixing iWarp and InfiniBand/RoCEv1/RoCEv2
port ranges used for smbdirect

- Fixes for smbdirect credit handling problems, these make
the connections more reliable

ksmbd: add procfs interface for runtime monitoring and statistics

This patch introduces a /proc filesystem interface to ksmbd, providing
visibility into the internal state of the SMB server. This allows
administrators and developers to monitor active connections, user
sessions, and opened files in real-time without relying on external
tools or heavy debugging.

Key changes include:
- Connection Monitoring (/proc/fs/ksmbd/clients): Displays a list of
active network connections, including client IP addresses, SMB dialects,
credits, and last active timestamps.

- Session Management (/proc/fs/ksmbd/sessions/): Adds a global sessions
file to list all authenticated users and their session IDs.

- Creates individual session entries (e.g., /proc/fs/ksmbd/sessions/<id>)
detailing capabilities (DFS, Multi-channel, etc.), signing/encryption
algorithms, and connected tree shares.

- File Tracking (/proc/fs/ksmbd/files): Shows all currently opened files
across the server, including tree IDs, process IDs (PID), access modes
(daccess/saccess), and oplock/lease states.

- Statistics & Counters: Implements internal counters for global server
metrics, such as the number of tree connections, total sessions, and
processed read/write bytes.
