Luis Henriques 6fd4e63483 ceph: allow object copies across different filesystems in the same cluster 
OSDs are able to perform object copies across different pools.  Thus,
there's no need to prevent copy_file_range from doing remote copies if the
source and destination superblocks are different.  Only return -EXDEV if
they have different fsid (the cluster ID).
