libxl: mark parameters in stub functions as unused

Hopefully this can fix issues like:

In file included from ../../src/libxl/xen_xl.c:24:0:
/home/osstest/build.147035.build-amd64-libvirt/xendist/usr/local/include/libxl.h: In function 'libxl_cpuid_apply_policy':

 static inline void libxl_cpuid_apply_policy(libxl_ctx *ctx, uint32_t domid) {}
