Peng Zhang cabdf74e6b mm: kfence: allocate kfence_metadata at runtime
kfence_metadata is currently a static array.  For the purpose of
allocating scalable __kfence_pool, we first change it to runtime
allocation of metadata.  Since the size of an object of kfence_metadata is
1160 bytes, we can save at least 72 pages (with default 256 objects)
without enabling kfence.
