Subject: drm/i915/guc: Don't pass CTB while reading
Git-commit: 235198d7c9bc9d632d801bd8b17cecf488212cc1
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Since we only have one RECV buffer we don't need to explicitly pass
it to the read function.
