Kobe Wu 9156e54576 locking/lockdep: increase size of counters for lockdep statistics 
When system has been running for a long time, signed integer
counters are not enough for some lockdep statistics. Using
unsigned long counters can satisfy the requirement. Besides,
most of lockdep statistics are unsigned. It is better to use
unsigned int instead of int.

Remove unused variables.
- max_recursion_depth
- nr_cyclic_check_recursions
- nr_find_usage_forwards_recursions
- nr_find_usage_backwards_recursions
