scsi: Do not rely on blk-mq for double completions

The scsi timeout error handling had been directly updating the request
state to prevent a natural completion and error handling from completing
the same request twice. Fix this layering violation by having scsi
control the fate of its commands with scsi owned flags rather than
use blk-mq's.
