[SCSI] scsi_error regression: Fix idempotent command handling

Drivers want to be able to return DID_TRANSPORT_DISRUPTED and
have it do the right thing for commands like tape and passthrouh
as far as retries go. The LLDs previously used DID_BUS_BUSY or DID_ERROR
which followed the cmd->retries limit, but DID_TRANSPORT_DISRUPTED
was skipping that check so it could have caused a problem with tape
commands.

This patch has DID_TRANSPORT_DISRUPTED check the cmd->retries/cmd->allowed.
