The structleak plugin causes the stack frame size to grow immensely:

drivers/thunderbolt/test.c:1529:1: error: the frame size of 1176 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

Turn it off in this file.

To me this is a reasonable work around so I can pick this up to
Thunderbolt tree if no objections.

Thanks BTW, for doing this. I got a report from buildbot some time ago
about the this but did not have time to figure out how to fix it :)
