Add partial support for QUERY TMF to CAM and isp(4).

Browse Source 
This change allows to decode respective functions in isp(4) in target mode
and pass them through CAM to CTL.  Unfortunately neither CAM nor isp(4)
support returning response info for those task management functions now.

On the other side I just have no initiator to test this functionality.
