ceph: allow sync_read/write return partial successed size of read/write. For sync_read/write, it may do multi stripe operations.If one of those met erro, we return the former successed size rather than a error value. There is a exception for write-operation met -EOLDSNAPC.If this occur,we retry the whole write again. Signed-off-by: Jianpeng Ma <majianpeng@gmail.com>
