Linux 4.6 compat: Fall back to d_prune_aliases() if necessary
As of 4.6, the icache and dcache LRUs are memcg aware insofar as the kernel's per-superblock shrinker is concerned. The effect is that dcache or icache entries added by a task in a non-root memcg won't be scanned by the shrinker in the context of the root (or NULL) memcg. This defeats the attempts by zfs_sb_prune() to unpin buffers and can allow metadata to grow uncontrollably. This patch reverts to the d_prune_aliaes() method in case the kernel's per-superblock shrinker is not able to free anything.
