[PATCH] tools/perf/tests: Fix session topology test comparison check

[Athira Rajeev <atrajeev@linux.vnet.ibm.com>]

commit cfd7092c31ae ("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. Patch fixes this
condition check.
