ocfs2: submit disk heartbeat bio using WRITE_SYNC
Under heavy I/O load, writing the disk heartbeat can be forced to wait for minutes, and this causes the node to be fenced. This patch tries to use WRITE_SYNC in submitting the heartbeat bio, so that writing the heartbeat will have a priority over other requests.
