Daniele Ceraolo Spurio e068ef3fd5 drm/i915/guc: Initialize GuC submission locks and queues early
Move initialization of submission-related spinlock, lists and workers to
init_early. This fixes an issue where if the GuC init fails we might
still try to get the lock in the context cleanup code. Note that it is
safe to call the GuC context cleanup code even if the init failed
because all contexts are initialized with an invalid GuC ID, which will
cause the GuC side of the cleanup to be skipped, so it is easier to just
make sure the variables are initialized than to special case the cleanup
to handle the case when they're not.
