9p/xen: fix init sequence
[ Upstream commit 7ef3ae82a6ebbf4750967d1ce43bcdb7e44ff74b ]
Large amount of mount hangs observed during hotplugging of 9pfs devices. The
9pfs Xen driver attempts to initialize itself more than once, causing the
frontend and backend to disagree: the backend listens on a channel that the
frontend does not send on, resulting in stalled processing.
Only allow initialization of 9p frontend once.
