lib/Kconfig.debug: correct help info of LOCKDEP_STACK_TRACE_HASH_BITS
We can see the following definition in kernel/locking/lockdep_internals.h:
#define STACK_TRACE_HASH_SIZE (1 << CONFIG_LOCKDEP_STACK_TRACE_HASH_BITS)
CONFIG_LOCKDEP_STACK_TRACE_HASH_BITS is related with STACK_TRACE_HASH_SIZE
instead of MAX_STACK_TRACE_ENTRIES, fix it.
