drm/i915/gvt: Fix error code in intel_gvt_init_device()
The intel_gvt_init_vgpu_type_groups() function is only called from
intel_gvt_init_device(). If it fails then the intel_gvt_init_device()
prints the error code and propagates it back again. That's a bug
because false is zero/success. The fix is to modify it to return zero
or negative error codes and make everything consistent.
