qemu: fix remote port searching

After fixing the last review comments on remote port searching (commit
a14b4aea), the commit right after that
wasn't modified accordingly, therefore two values weren't changed as
they should and the configurable ports don't work as expected.

This simple commit changes last two values missed and fixes the issue.
