virtio_dev can now be freed via virtio_dev_deinit.
While here, also rename virtio_init_device to
virtio_dev_init for name consistency.
This patch also adds some error-checking.

Generic virtio_dev has the same field already.
The field was previously used to store vhost-user
GET_QUEUE_NUM response, that will be later assigned
to virtio_dev->max_queues via virtio_user_read_dev_config.
This patch removes virtio_user_dev->max_queues
with entire virtio_user_read_dev_config functionality
for virtio_user.

Moved negotiation to virtio_init_device.
This patch also cleans up feature negotiation a bit.

Previously virtio_hw was managing both VirtIO PCI and
vhost-user devices. Now's there virtio_dev, a common
part for both backends. virtio_hw is only used for PCI.
Note that this patch does not introduce another
abstraction layer. It only unifies an already existing
one. Previously virtio_user_dev was built on top of
virtio_hw, with most PCI fields just hanging there
unused. Now both, virtio_user_dev and virtio_hw are
built on top of virtio_dev.
