[ Upstream commit b236371421df57b93fc49c4b9d0e53bd1aab2b2e ]
commit cfd7092c31aed728 ("perf test session topology: Fix test to skip the test in guest environment") added check to skip the testcase if the socket_id can't be fetched from topology info.
But the condition check uses strncmp which should be changed to !strncmp and to correctly match platform.
Fix this condition check.
