Subject: [PATCH] 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.

Fixes: 5dc33592e955 ("lockdep: Allow tuning tracing capacity constants.")
