hw/9pfs: use migration blockers to prevent live migration when virtfs export path is mounted
Now when you try to migrate with VirtFS export path mounted, you get a proper QMP error:
(qemu) migrate tcp:localhost:4444
Migration is disabled when VirtFS export path '/tmp/' is mounted in the guest using mount_tag 'v_tmp'
(qemu)
