Some of the internal functions used to return the
number of bytes associated with a successfully submitted
IO, but that was changed a while ago to just return 0
for success.
So change some of the callers of these functions to
just look for != 0 for failure rather than < 0. This
preps for some upcoming ENOMEM handling changes.
