Commands that are reset are returned with status SAM_STAT_COMMAND_TERMINATED. PVSCSI currently returns DID_OK | SAM_STAT_COMMAND_TERMINATED which fails the command. Instead, set hostbyte to DID_RESET to allow upper layers to retry. Tested by copying a large file between two pvscsi disks on same adapter while performing a bus reset at 1-second intervals. Before fix, commands sometimes fail with DID_OK. After fix, commands observed to fail with DID_RESET.
