[LU-3868] lockless IO does not update inode timestamps

Description

In osc_io_read_start() and osc_io_write_start() if the lockless IO bit is set in the osc_io then the inode timestamps are not updated by the IO. Is there any reason for this?

In osc_io_write_start() we have the following unnecessary attr get before we set the m- and c-times?

                result = cl_object_attr_get(env, obj, attr);
                if (result == 0) {
			attr->cat_mtime = attr->cat_ctime =
                                LTIME_S(CFS_CURRENT_TIME);
                        result = cl_object_attr_set(env, obj, attr,
                                                    CAT_MTIME | CAT_CTIME);
                }
