[XFS] A problem was found with the debug code in xlog_state_do_callback. At

the end of processing all log buffers that can be processed, there is
a (debug only) double-check to make sure that log buffers with
completed I/O don't get marooned when the function completes.  The
check only needs to go to the first buffer that will cause an I/O
completion, that has not completed.  The loop doesn't stop a WANT_SYNC
state buffer is found, but it should.
