drm/i915: Wake device for emitting request during selftest
igt_mmap_offset_exhaustion() selftest was using live requests to make an object busy, but we did not hold a runtime pm wakeref for submitting the requests. Acquire it to avoid triggering "RPM wakelock ref not held during HW access" warnings.
