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.
