[Intel-gfx] [PATCH v3 6/6] drm/i915/uc: do not free err log on uc_fini

[Daniele Ceraolo Spurio]

We need to keep the GuC error logs around to debug the load failure,
so we can't clean them in the error unwind, which includes uc_fini().
Moving the cleanup to driver remove ensures that the logs stick around
long enough for us to dump them.

v2: reword commit msg (John)
