Harry Yoo 7fa46cdfff mm/kasan: use SLAB_NO_MERGE flag instead of an empty constructor
Use SLAB_NO_MERGE flag to prevent merging instead of providing an empty
constructor.  Using an empty constructor in this manner is an abuse of
slab interface.

The SLAB_NO_MERGE flag should be used with caution, but in this case, it
is acceptable as the cache is intended solely for debugging purposes.

No functional changes intended.
