[PATCH mm-unstable v1 18/20] RDMA/hw/qib/qib_user_pages: remove FOLL_FORCE usage

[David Hildenbrand]

FOLL_FORCE is really only for ptrace access. As we unpin the pinned pages
using unpin_user_pages_dirty_lock(true), the assumption is that all these
pages are writable.

FOLL_FORCE in this case seems to be a legacy leftover. Let's just remove
it.
