Andrey Konovalov 2e7c954c11 kasan: add return value for kasan_mempool_poison_object
Add a return value for kasan_mempool_poison_object that lets the caller
know whether the allocation is affected by a double-free or an
invalid-free bug.  The caller can use this return value to stop operating
on the object.

Also introduce a check_page_allocation helper function to improve the code
readability.
