[PATCH 06/12] drm/i915/guc: Only release GuC log object during submission_fini

[Sagar Arun Kamble]

GuC log runtime/relay channel data is released during i915 unregister,
so only GuC log vma needs to be released during submission_fini.

v2: Refined usage of intel_guc_log_destroy and created new function
intel_guc_log_runtime_destroy. (Tvrtko)
