[PATCH 2/3] selftests/powerpc: Don't use setaffinity in tm-tmspr

[Michael Ellerman]

This test tries to set affinity to CPUs that don't exist, especially
if the set of online CPUs doesn't start at 0.

But there's no real reason for it to use setaffinity in the first
place, it's just trying to create lots of threads to cause contention.
So drop the setaffinity entirely.
