x86: make DEBUG_PAGEALLOC and CPA more robust
Use PF_MEMALLOC to prevent recursive calls in the DBEUG_PAGEALLOC
case. This makes the code simpler and more robust against allocation
failures.
This fixes the following fallback to non-mmconfig:

Also, for DEBUG_PAGEALLOC=n reduce the pool size to one page.
