scsi-disk: Clear aiocb on read completion
Once the I/O completion callback returned, aiocb will be released by the
controller. So we have to clear the reference not only in
scsi_write_complete, but also in scsi_read_complete. Otherwise we risk
inconsistencies when a reset hits us before the related request is
released.
