[RFC 11/60] locking/lockdep: Increase number of supported lockdep subclasses

[Jan H. SchÃnherr]

With coscheduling the number of required classes is twice the depth of
the scheduling domain hierarchy. For a 256 CPU system, there are eight
levels at most. Adjust the number of subclasses, so that lockdep can
still be used on such systems.
