drm/i915/gt: ce->inflight updates are now serialised
Since schedule-in and schedule-out are now both always under the tasklet
bitlock, we can reduce the individual atomic operations to simple
instructions and worry less.
This notably eliminates the race observed with intel_context_inflight in
__engine_unpark().
