hugetlb: rename remove_huge_page to hugetlb_delete_from_page_cache

remove_huge_page removes a hugetlb page from the page cache.  Change to
hugetlb_delete_from_page_cache as it is a more descriptive name.
huge_add_to_page_cache is global in scope, but only deals with hugetlb
pages.  For consistency and clarity, rename to hugetlb_add_to_page_cache.
