From: Prasanna Mumbai <prasanna.mumbai@xxxxxxxxxx>
Complete the cmd if sense length is zero. For cases where sense
data spans across multiple iocb's by FW, we need to hold on to the
I/O (ha->status_srb != NULL) till we have processed them all and
copied the sense data from internal buffer to scsi_cmd sense buffer.
