Guest module parameter is not the correct way of detetecting if host
has GuC submission enabled. And even if it was, the message is overly
verbose (and it'll be incorrect once i915.enable_guc_submission
defaults to something else than zero).

The original patch should've included at least some Cc's, or wait being
merged through drm-tip as it's not int drm/i915/gvt directory at all
(unlike the message states).
The patch should be reverted for being incorrect.
