[PATCH v2 03/13] mm/gup: don't call __gup_longterm_locked() if FOLL_LONGTERM cannot be set

[Jason Gunthorpe <jgg@nvidia.com>]

get_user_pages_remote(), get_user_pages_unlocked() and get_user_pages()
are never called with FOLL_LONGTERM, so directly call
__get_user_pages_locked()

The next patch will add an assertion for this.
