block/iscsi: handle BUSY condition
this patch adds handling of BUSY status reponse from an iSCSI target.
Currently, we fail with -EIO in case of SCSI_STATUS_BUSY while the
obvious reaction would be to retry the operation after some time.
The retry time is randomly choosen from a range with exponential
growth increasing with each retry.
This patch includes most of the changes by a an upcoming patch
from Stefan Hajnoczi:
iscsi: implement .bdrv_detach/attach_aio_context()
because I also need the reference to the aio_context for
the retry timer to work. I included the changes to maintain
better mergeability.
