Revert "scsi: core: return BLK_STS_OK for DID_OK in __scsi_error_from_host_byte()"
The description of commit e39a97353e53 is wrong: it mentions that commit 2a842acab109 introduced a bug in __scsi_error_from_host_byte() although that commit did not change the behavior of that function. Additionally, commit e39a97353e53 introduced a bug: it causes commands that fail with hostbyte=DID_OK and driverbyte=DRIVER_SENSE to be completed with BLK_STS_OK. Hence revert that commit.
