[PATCH] scsi: return BLK_STS_OK for DID_OK in __scsi_error_from_host_byte()

[Hannes Reinecke]

When converting __scsi_error_from_host_byte() to BLK_STS error codes
the case DID_OK was forgotten, resulting in it always returning
an error.

Fixes: 2a842acab109 ("block: introduce new block status code type")
