Chris Wilson ea26c96d59 drm/i915/gvt: Fix out-of-bounds buffer write into opregion->signature[] ...

sparse spots

drivers/gpu/drm/i915/gvt/opregion.c:234 alloc_and_init_virt_opregion() error: memcpy() 'header->signature' too small (16 vs 17)

as gvt is indeed trying to memcpy a string longer than the signature[].
