vdpa-dev: get iova range explicitly

Browse Source 
In commit a585fad26b ("vdpa: request iova_range only once") we remove
GET_IOVA_RANGE form vhost_vdpa_init, the generic vdpa device will start
without iova_range populated, so the device won't work. Let's call
GET_IOVA_RANGE ioctl explicitly.

Fixes: a585fad26b ("vdpa: request iova_range only once")
