[dpdk-stable] [PATCH v16.11 LTS] vhost: fix compilation issue when vhost debug enabled

[Maxime Coquelin]

This patch fixes below compilation issue when
RTE_LIBRTE_VHOST_DEBUG is enabled:

In file included from /home/max/projects/src/mainline/dpdk/lib/librte_vhost/virtio_net.c:50:0:
./lib/librte_vhost/virtio_net.c: In function ‘copy_mbuf_to_desc’:
./lib/librte_vhost/vhost.h:205:42: warning: format ‘%d’ expects argument of type ‘int’, but argument 5 has type ‘uint64_t {aka long unsigned int}’ [-Wformat=]
   snprintf(packet, VHOST_MAX_PRINT_BUFF, "(%d) Header size %d: ", (device->vid), (size)); \
                                          ^
/home/max/projects/src/mainline/dpdk/lib/librte_vhost/virtio_net.c:301:4: note: in expansion of macro ‘PRINT_PACKET’
    PRINT_PACKET(dev, (uintptr_t)dst, len, 0);
    ^~~~~~~~~~~~

Fixes: 067047a90055 ("vhost: handle virtually non-contiguous buffers in Tx")
Fixes: dd906b814d9a ("vhost: handle virtually non-contiguous buffers in Rx")
Fixes: 2b8d39414619 ("vhost: handle virtually non-contiguous buffers in Rx-mrg")
