teeio-validator can't find free port when running 4 link stream tests

[mxu9]

It looks like when we run the IDE enabling for second port at that time, it doesn’t find any free port (Basically it is looking at the registers on Port0).

1. ./teeio_validator -f link_ide_x4x4x4x4.ini -t 1 -c 1 -s Test.IdeStream  Port0 works fine.
2. ./teeio_validator -f link_ide_x4x4x4x4.ini -t 2 -c 1 -s Test.IdeStream  Port1 seems to be having issues. Because it is still looking at the registers in Port0.

After setting up the Link stream on Port1, I checked the Stream Control B registers and they seem to be still showing as 0.
