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.
