smb: client: Fix NULL pointer dereference in cifs_debug_dirs_proc_show()
Reading /proc/fs/cifs/open_dirs may hit a NULL dereference when
tcon->cfids is NULL.
Add NULL check before accessing cfids to prevent the crash.
Reproduction:
- Mount CIFS share
- cat /proc/fs/cifs/open_dirs
Fixes: 844e5c0eb176 ("smb3 client: add way to show directory leases for improved debugging")
