[libvirt PATCH 01/16] qemu: vhost-user-fs: format alias on the command line

[Ján Tomko]

The commit adding the vhost-user-fs device forgot to format
the device's alias on the command line.

Thankfully it was not needed yet because virtiofs migration
is not yet supported, but it will be needed in the future
to allow hot(un)plug.
