ocfs2: Rename ocfs2_cp_xattr_cluster() to ocfs2_mv_xattr_buckets().
ocfs2: Rename ocfs2_cp_xattr_cluster() to ocfs2_mv_xattr_buckets().

ocfs2_cp_xattr_cluster() takes the last cluster of an xattr extent,
copies its buckets to the front of a new extent, and then shrinks the bucket
count of the original extent.  So it's really moving the data, not
copying it.

While we're here, the function doesn't need a buffer_head for the old
extent, just the block number.
