scsi: NCR5380: Handle BSY signal loss during information transfer phases

Browse source

Improve robustness by checking for a lost BSY signal during the information
transfer loop. The status register is being polled anyway, so a BSY check
costs nothing. BSY signal loss could be caused by a target error or a
kicked plug etc. A bus reset is another possibility but that is already
handled and hostdata->connected would be NULL.
