This ensures that all spdk_bdev_io structures now have
an attached channel, simplifying some future work around
things like counting the number of outstanding IOs for
a given channel (which otherwise would have had to
account specially for resets).
Reset semantics are still that they affect the entire bdev
and not just the channel it was submitted on.

Replace the spdk_bdev_io_completion_cb status parameter with a bool
simply indiciating whether the I/O completed successfully.
