qdev: fix get_fw_dev_path to support to add nothing to fw_dev_path

Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path...

virtio-pci: fix level interrupts

mask notifiers are never called without msix,
so devices with backend masking like vhost don't work.
Call mask notifiers explicitly at

virtio: properly validate address before accessing config

There are several several issues in the current checking:

- The check was based on the minus of unsigned values which can overflow
- It was done after .{set|get}_config() which can lead crash when config_len...

virtio-x-bus: force bus name to virtio-bus.

When the proxy id is set, this bus takes the name "id.0" which is expected
to be the virtio-device's first bus.

So force this name to "virtio-bus" as it is an internal bus.
