drm/i915: Generate the engine name based on the instance number
Not really needed, but makes the next change a little bit more compact.
v2:
- Use zero-based numbering for engine names: xcs0, xcs1.. xcsN (Tvrtko, Chris)
- Make sure the mock engine name is null-terminated (Tvrtko, Chris)
v3: Because I'm stupid (Chris)
v4: Verify engine name wasn't truncated (Michal)
v5:
- Kill the warning in mock engine (Chris)
