[PATCH v1 2/3] drm/xe/drm_ras: Make counter allocation drm managed

[Raag Jadav <raag.jadav@intel.com>]

cleanup_node_param() is not registered in case of counter allocation
failure, which results in stale memory of previous node that isn't
cleaned up on unwind. Fix this using drm managed allocation, which is
guaranteed to be cleaned up on unwind.
