[PATCH 1/3] vhost: fix build for powerpc

[Bruce Richardson]

When building on Ubuntu using the packaged powerpc compiler[1], a
warning is issued about the print format of the __u64 values.

../../lib/vhost/vduse.c: In function ‘vduse_vring_setup’:
../../lib/vhost/vhost.h:676:17: error: format ‘%llx’ expects argument of
type ‘long long unsigned int’, but argument 5 has type ‘__u64’ {aka
‘long unsigned int’} [-Werror=format=]
  676 |                 "VHOST_CONFIG: (%s) " fmt, prefix, ##args)
      |                 ^~~~~~~~~~~~~~~~~~~~~

Changing the format specifier to %lx, or to use PRIx64 breaks other
builds, so the safest solution is to explicitly typecast the printed
values to match the format string.

[1] powerpc64le-linux-gnu-gcc (Ubuntu 12.3.0-1ubuntu1~23.04) 12.3.0
