[PATCH i-g-t] tests/intel/xe_pm_residency: Skip on igt_power_open failure

[Jonathan-Cavitt <jonathan.cavitt@intel.com>]

The xe_pm_residency@toggle-gt-c6 test fails when
gt_c6_power >= gt_c0_power.  These values are reported by
igt_power_get_mW, which will always report 0 in the case that
igt_power_open fails to open either the hwmon_fd or rapl.fd.  Since the
expected result will always be a failure in this case, skip the test to
end execution early.
