drm/i915/huc: fix leak of debug object in huc load fence on driver unload
The fence is always initialized in huc_init_early, but the cleanup in
huc_fini is only being run if HuC is enabled. This causes a leaking of
the debug object when HuC is disabled/not supported, which can in turn
trigger a warning if we try to register a new debug offset at the same
address on driver reload.
To fix the issue, make sure to always run the cleanup code.
