When a tmf is issued, various response codes can be
returned from the target. For a query tmf the
response may be TMF_RESP_FUNC_COMPLETE or
TMF_RESP_FUNC_SUCC.
Add a condition for TMF_RESP_FUNC_SUCC.
Also, check for SAM_STAT_GOOD is replaced with
TMF_RESP_FUNC_COMPLETE, which is a genuine tmf
response code. SAM_STAT_GOOD and
TMF_RESP_FUNC_COMPLETE have the same value, so
this is why it worked before.
