drm/i915/gem: Use large rings for compute contexts
Allow compute contexts to submit the maximal amount of work without
blocking userspace.
The original size for user LRC ring's (SZ_16K) was chosen to minimise
memory consumption, without being so small as to frequently stall in the
middle of workloads. With the main consumers being GL / media pipelines
of 2 or 3 batches per frame, we want to support ~10 requests in flight
to allow for the application to control throttling without stalling
within a frame.
v2:
- cover with else part
