[PATCH v1 1/3] drm/ras: Cancel and free message on get counter failure

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

doit_reply_value() directly returns on get counter failure, which results
in stale sk_buff and genetlink header that aren't cleaned up. Fix it.

Fixes: c36218dc49f5 ("drm/ras: Introduce the DRM RAS infrastructure over generic netlink")
