[PATCH] net/sfc: do not spam logs on tunnel restore info errors

[PATCH] net/sfc: do not spam logs on tunnel restore info errors

[Ivan Malov]

OvS might invoke this API on its data path, out of sync
with its control plane. If the control path has already
deactivated the tunnel context entry, these invocations
will produce quite a few error printouts. Suppress that.
