drm/i915/guc: Remove excessive line feeds in state dumps

Some of the GuC state dump messages were adding extra line feeds. When
printing via a DRM printer to dmesg, for example, that messes up the
log formatting as it loses any prefixing from the printer. Given that
the extra line feeds are just in the middle of random bits of GuC
state, there isn't any real need for them. So just remove them
completely.
