drm/xe/debugfs: Get a runtime_pm reference when setting wedged mode 



This function is another entry point where it must be ensured that
the device resumes before operating on the GuC, so grab a runtime_pm
reference. This fixes inner xe_pm_runtime_get_noresume calls which
were previously failing.
