Currently there is no way to figure out if an write error occurred.  Buffers
with an write error will be discarded.  We should consider to return an
cumulative error status from the rtems_bdbuf_{sync/syncdev} functions.  We
should return:

 o RTEMS_SUCCESSFUL Operation was successful
 o RTMES_IO_ERROR Low-level synchronization failed or write error occurred
between last synchronization request or disk creation

The cumulative error status should be maintained on a per physical disk level.
