Today the connection sequence of the Xen 9pfs frontend doesn't match
the documented sequence. It can work reliably only for a PV 9pfs device
having been added at boot time already, as the frontend is not waiting
for the backend to have set its state to "XenbusStateInitWait" before
reading the backend properties from Xenstore.

Fix that by following the documented sequence [1] (the documentation
has a bug, so the reference is for the patch fixing that).

It's unclear if this series is targeted at 'net' or 'net-next'.
FWIIW, I feel I feel it would be more appropriate for the latter
as these do not feel like bug fixes: feel free to differ on that.

Regardless,
