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. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
