[PATCH v2 2/2] drm/xe: fix unbalanced rpm put() with declare_wedged()

[Matthew Auld]

Technically the or_reset() means we call the action on failure, however
that would lead to unbalanced rpm put(). Move the get() earlier to fix
this. It should be extremely unlikely to ever trigger this in practice.
