xfs: support idmapped mounts
Enable idmapped mounts for xfs. This basically just means passing down the user_namespace argument from the VFS methods down to where it is passed to the relevant helpers. Note that full-filesystem bulkstat is not supported from inside idmapped mounts as it is an administrative operation that acts on the whole file system. The limitation is not applied to the bulkstat single operation that just operates on a single inode.
