scsi: csiostor: fix missing data copy in csio_scsi_err_handler()

Browse Source 
[ Upstream commit 5c2442fd78 ]

If scsi cmd sglist is not suitable for DDP then csiostor driver uses
preallocated buffers for DDP, because of this data copy is required from
DDP buffer to scsi cmd sglist before calling ->scsi_done().
