Jim Harris a0d7056f11 copy: return 0 on success and appropriate errno on failure
This code was still using an old paradigm of returning the
number of bytes associated with a successful submission.
Just return 0 on success instead - if caller needs the
number of bytes for some reason they have the information
to get it.

While here, return an appropriate negated errno where possible -
we especially want ENOMEM returned when an ioat channel runs out
of descriptors.
