Subject: drm/i915: Mark up inline getters as taking a const i915_request
Git-commit: e971fe9128a742537a1d8803b852c69777a885eb
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Since these inline routines only return the desired pointer from the
i915_request(after checking the preconditions for acquiring said
pointer), they can be const.
