drm/xe: Fix the gem shrinker name

The xe buffer object shrinker name is visible in the
<debugfs>/shrinker directory and most if not all other shinkers
follow a naming convention that looks like
<subsystem>-<driver>_<objects>:<unique>
Follow the same convention for xe, changing the name to
drm-xe_gem:<unique>.

Other shrinkers typically use the device node for <unique> but
since drm drivers typically don't have a single unique device-
node, instead use the unique name in the drm device.
