virtio-9p: use aliases instead of duplicate qdev properties

virtio-9p-pci all duplicate the qdev properties of their
V9fsState child. This approach does not work well with
string or pointer properties since we must be careful
about leaking or double-freeing them.

Use the QOM alias property to forward property accesses to the
V9fsState child.  This way no duplication is necessary.
