drm/etnaviv: add lockdep annotation for userptr object population
The current userptr page population will defer work to a work item if needed to avoid ever taking the mmap_sem in the direct call path. With the more fine-grained locking in etnaviv this isn't needed anymore, so a future commit will simplify this code. Add a lockdep annotation to validate the assumption that the mmap_sem can be taken in the direct call path.
