locking/lockdep: Remove hard coded array size dependency
An apparent oversight left a hardcoded '4' in place when
LOCKSTAT_POINTS was introduced.
The contention_point[] and contending_point[] arrays in the
structs lock_class and lock_class_stats need to be the same
size for the loops in lock_stats() to be correct.
This patch allows LOCKSTAT_POINTS to be changed without
affecting the correctness of the code.
