infiniband-diags/iblinkinfo.c: Limit certain queries to switches

iblinkinfo man page says:
DESCRIPTION
        iblinkinfo reports the link info for each port of each switch 
active in
        the IB fabric.

OPTIONS
        -S <guid>
               Output only the switch specified by <guid> (hex format)

        -D <direct_route>
               Output only the switch specified by the direct route path.

Queries by DR path or GUID should (also) be limited to switches.
