drm/gem: Add ww_acquire_ctx support to drm_gem_lru_scan()
If the callback is going to have to attempt to grab more locks, it is
useful to have an ww_acquire_ctx to avoid locking order problems.
Why not use the drm_exec helper instead? Mainly because (a) where
ww_acquire_init() is called is awkward, and (b) we don't really
need to retry after backoff, we can just move on to the next object.
