habanalabs: remove FOLL_FORCE usage

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 due to copy-and-past from other
drivers. Let's just remove it.
