ide-cd: Do not access completed requests in the irq handler

commit 110712828365ccafcc61a7f4db44c31ed4cf8793 upstream.

ide_cd_error_cmd() can complete an erroneous request with leftover
buffers. Signal this with its return value so that the request is not
accessed after its completion in the irq handler and we oops.
