mm/gup: check FOLL_CMA eariler than others

__need_migrate_cma_page() checks a lot of conditions if the current
get_user_pages() request need to migrate CMA pages to some other pages.
But FOLL_CMA is given by very few users. We don't need to spend time
for condition check for the users without FOLL_CMA.
