Revert "mm: create a separate slab for page->ptl allocation"
This reverts commit ea1e7ed33708c7a760419ff9ded0a6cb90586a50. Al points out that while the commit *does* actually create a separate slab for the page->ptl allocation, that slab is never actually used, and the code continues to use kmalloc/kfree. Damien Wyart points out that the original patch did have the conversion to use kmem_cache_alloc/free, so it got lost somewhere on its way to me. Revert the half-arsed attempt that didn't do anything. If we really do want the special slab (remember: this is all relevant just for debug builds, so it's not necessarily all that critical) we might as well redo the patch fully.
