xfs: per-filesystem dquot LRU lists
Replace the global dquot lru lists with a per-filesystem one. Note that the shrinker isn't wire up to the per-superblock VFS shrinker infrastructure as would have problems summing up and splitting the counts for inodes and dquots. I don't think this is a major problem as the quota cache isn't as interwinded with the inode cache as the dentry cache is, because an inode that is dropped from the cache will generally release a dquot reference, but most of the time it won't be the last one.
