ksmbd: use scoped_with_init_fs() for VFS path operations

Browse source

Use scoped_with_init_fs() to temporarily override current->fs for
path lookups in ksmbd VFS helpers:
- ksmbd_vfs_path_lookup(): wrap vfs_path_parent_lookup()
- ksmbd_vfs_link(): wrap kern_path() for old path resolution
- ksmbd_vfs_kern_path_create(): wrap start_creating_path()

This ensures path lookups happen in init's filesystem context.

All ksmbd paths ← SMB command handlers ← handle_ksmbd_work() ← workqueue
← ksmbd_conn_handler_loop() ← kthread
