We map the initial context during first pin.
This allows us to remove pin_map from state allocation, which saves
us a few retry loops. We won't need this until first pin anyway.
intel_ring_submission_setup() is also reworked slightly to do all
pinning in a single ww loop.
Changes since v1:
- Handle -EDEADLK backoff in intel_ring_submission_setup() better.
- Handle smatch errors reported by Dan and testbot.
