scsi: NCR5380: Handle PDMA failure reliably

commit f9dfed1c785734b95b08d67600e05d2092508ab0 upstream.

A PDMA error is handled in the core driver by setting the device's 'borken'
flag and aborting the command. Unfortunately, do_abort() is not
dependable. Perform a SCSI bus reset instead, to make sure that the command
fails and gets retried.
