panvk: Silence warning on incompatible DRM render devices

This message is printed on non-panfrost/panthor systems on every
physical device enumeration when panvk is present like in distribution
mesa builds.
This "breaks" gtk-4 tests in the default configuration since they fail
on warning log messages. gtk-4 still forwards the vulkan debug report as
warning messages after fixes for issue 11451 to stop handling it as
critical message.
