mm/gup.c: reorganize try_get_folio()
try_get_folio() takes in a page, then chooses to do some folio operations
based on the flags (either FOLL_GET or FOLL_PIN). We can rewrite this
function to be more purpose oriented.
After calling try_get_folio(), if neither FOLL_GET nor FOLL_PIN are set,
warn and fail. If FOLL_GET is set we can return the result. If FOLL_GET
is not set then FOLL_PIN is set, so we pin the folio.
This change assists with folio conversions, and makes the function more
readable.
