[BLOCK] update IDE to use new blk_ordered for barriers
Update IDE to use new blk_ordered. This change makes the
following behavior changes.
* Partial completion of the barrier request is handled as
failure of the whole ordered sequence. No more partial
completion for barrier requests.
* Any failure of pre or post flush request results in failure
of the whole ordered sequence.
So, successfully completed ordered sequence guarantees that
all requests prior to the barrier made to physical medium and,
then, the while barrier request made to the physical medium.
