drm/i915/guc: Make intel_guc_recv static.

Browse Source 
This function is only used by intel_guc_send() and it doesn't
need to be exposed outside of intel_uc.o file. Also when defined
as static, compiler will generate smaller code. Additionally let
it take guc param instead dev_priv to match function name.
