HARDWARE ERROR sense is very strong considered be "internal failure", so
might lead to serios initiator side issues up to disconnect from device. In
many cases WRITE or READ ERROR sense can be used instead. All remaining
usages must be logged.

606af43444 scst_vdisk: Avoid triggering BUG() for large LBA's 
The LBA field in READ(16) and READ(32) commands is 64 bits wide.
Hence it is possible for an initiator not only to specify an offset
that exceeds 2**63. Report an error to the initiator for such large
offsets instead of triggering a BUG().  This patch fixes the following bug:
