drm/i915: don't make assumptions about intel_wakeref_t type

Browse source 
intel_wakeref_t is supposed to be a mostly opaque cookie to its
users. It should only be checked for being non-zero and set to
zero. Debug logging its actual value is meaningless. Switch to just
debug logging whether the async_put_wakeref is non-zero.

The issue dates back to much earlier than
commit b49e894c3f ("drm/i915: Replace custom intel runtime_pm tracker
with ref_tracker library"), but this is the one that brought about a
build failure due to the printf format.
