smb: client: account smb directory cache usage and per-tcon totals

Add lightweight accounting for directory lease cache usage
to aid debugging and limiting cache size in future. Track
per-directory entry/byte counts and maintain per-tcon
aggregates. Also expose the totals in /proc/fs/cifs/open_dirs.
