mm/gup: make locked never NULL in the internal GUP functions
Now that NULL locked doesn't have a special meaning we can just make it
non-NULL in all cases and remove the special tests.
get_user_pages() and pin_user_pages() can safely pass in a locked = 1
get_user_pages_remote) and pin_user_pages_remote() can swap in a local
variable for locked if NULL is passed.
Remove all the NULL checks.
