[PATCH 2/2] libvhost-user: fix -Werror=format= warnings with __u64 fields |

../subprojects/libvhost-user/libvhost-user.c:1070:12: error: format ‘%lx’
expects argument of type ‘long unsigned int’, but argument 3 has type ‘__u64’
{aka ‘long long unsigned int’} [-Werror=format=]
1070 | DPRINT(" desc_user_addr: 0x%016" PRIx64 "\n",
vra->desc_user_addr);

| __u64 {aka
long long unsigned int}
Rather than using %llx, which may fail if __u64 is declared differently
elsewhere, let's just cast the values. Feel free to propose a better solution!
