ioat: fix type mismatch for ->dmacount
->dmacount tracks the sequence number of active descriptors. It is
written to the DMACOUNT register to update the channel's view of pending
descriptors in the chain. The register is 16-bits so ->dmacount should
be unsigned and 16-bit as well. Also modify ->desccount to maintain
alignment.
This was never a problem in practice because we never compared dmacount
values, but this is a bug waiting to happen.
