ide-iops: fix odd-length ATAPI PIO transfers

commit a509538d4fb4f99cdf0a095213d57cc3b2347615 upstream.

Commit 9567b349f7e7dd7e2483db99ee8e4a6fe0caca38 (ide: merge ->atapi_*put_bytes
and ->ata_*put_data methods) introduced a regression  WRT the odd-length ATAPI
PIO transfers -- the final word didn't get written (causing command timeouts).
