xen-netback: making the bandwidth limiter runtime settable
With the current netback, the bandwidth limiter's parameters are only
settable during vif setup time. This patch register a watch on them, and
thus makes them runtime changeable.
When the watch fires, the timer is reset. The timer's mutex is used for
fencing the change.
