I think a bug exists in the sync code. The
rtems_bdbuf_swapout_modified_processing call sets the timer to 0 of all buffers
on the list but they may not be on the device asked to be sync'ed.

The solution is to detect if a sync of all buffers has been asked. This is
indicated by the dev field being invalid. Currently you can only sync a
specific bd or a device. There is no whole cache sync call.
