mm: kfence: apply kmemleak_ignore_phys on early allocated pool
This patch solves two issues.
(1) The pool allocated by memblock needs to unregister from
kmemleak scanning. Apply kmemleak_ignore_phys to replace the
original kmemleak_free as its address now is stored in the phys tree.
(2) The pool late allocated by page-alloc doesn't need to unregister.
Move out the freeing operation from its call path.
