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, that commit introduced a severe bug: it causes commands
that fail with hostbyte=DID_OK and driverbyte=DRIVER_SENSE to be
completed with BLK_STS_OK. Although that commit claims to fix a bug
it does not mention which bug it fixes. Hence revert that commit.
