mm/gup: make get_user_pages_fast_only() return the common return value
There are only two callers, both can handle the common return code: - get_user_page_fast_only() checks == 1 - gfn_to_page_many_atomic() already returns -1, and the only caller checks for negative return values Remove the restriction against returning negative values.
