Wei Liu 816843a257 xen-netback: correctly schedule rate-limited queues 
[ Upstream commit dfa523ae9f ]

Add a flag to indicate if a queue is rate-limited. Test the flag in
NAPI poll handler and avoid rescheduling the queue if true, otherwise
we risk locking up the host. The rescheduling will be done in the
timer callback function.
