powerpc/sstep: Fix emulate_step test if VSX not present
emulate_step() tests are failing if VSX is not supported or disabled. emulate_step_test: lxvd2x : FAIL emulate_step_test: stxvd2x : FAIL If !CPU_FTR_VSX, emulate_step() failure is expected and testcase should PASS with a valid justification. After patch: emulate_step_test: lxvd2x : PASS (!CPU_FTR_VSX) emulate_step_test: stxvd2x : PASS (!CPU_FTR_VSX) Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
