fix the NO_CCB handling i broke when working on simplifying the midlayer.
marco@ discovered my rewrite retried commands rejected by an adapter
from a timeout, which was trivially starved by normal io going to
disks. this diff allows an xs to be marked as XS_NO_CCB, which will
cause it to be returned to the device driver to be retried as part
of the normal io queue.
