examples/vhost_xen: fix 32-bit build

Compilation fails on 32 bits on Vhost_xen sample app, due to wrong casting:

examples/vhost_xen/vhost_monitor.c: In function ‘new_device’:
examples/vhost_xen/vhost_monitor.c:288:62: error: cast from pointer to integer
                               of different size [-Werror=pointer-to-int-cast]

Fixes: 47bd46112b71 ("xen: import xenvirt pmd and vhost_xen")
