mm, x86: Remove debug_pagealloc_enabled
When (no)bootmem finish operation, it pass pages to buddy allocator. Since debug_pagealloc_enabled is not set, we will do not protect pages, what is not what we want with CONFIG_DEBUG_PAGEALLOC=y. To fix remove debug_pagealloc_enabled. That variable was introduced by commit 12d6f21e "x86: do not PSE on CONFIG_DEBUG_PAGEALLOC=y" to get more CPA (change page attribude) code testing. But currently we have CONFIG_CPA_DEBUG, which test CPA.
