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[].
Fixes: b2d6ef70614e ("drm/i915/gvt: Let each vgpu has separate opregion memory")
