[3/4] CI_ONLY: pass request (not client) to i915_guc_wq_check_space()

Commit Message

Dave Gordon April 25, 2016, 2:37 p.m. UTC

The knowledge of how to derive the relevant client from the request
should be localised within i915_guc_submission.c; the LRC code shouldn't
have to know about the internal details of the GuC submission process.
