mm/page_alloc: reduce fallbacks to (MIGRATE_PCPTYPES - 1)

Browse source

The commit 1dd214b8f2 ("mm: page_alloc: avoid merging non-fallbackable
pageblocks with others") has removed MIGRATE_CMA and MIGRATE_ISOLATE from
fallbacks list. so there is no need to add an element at the end of every
type.

Reduce fallbacks to (MIGRATE_PCPTYPES - 1).
