mm: remove write/force parameters from __get_user_pages_unlocked()
commit d4944b0ecec0af882483fe44b66729316e575208 upstream.
This removes the redundant 'write' and 'force' parameters from
__get_user_pages_unlocked() to make the use of FOLL_FORCE explicit in
callers as use of this flag can result in surprising behaviour (and
hence bugs) within the mm subsystem.

[bwh: Backported to 4.4:
- Defer changes in process_vm_rw_single_vec() and async_pf_execute() since
they use get_user_pages_unlocked() here
- Adjust context]
