gianfar: Remove 'maybe-uninitialized' compile warning
Warning message: warning: 'budget_per_q' may be used uninitialized in this function budget_per_q won't be used uninitialized since the only time it doesn't get initialized is when entering gfar_poll with num_act_queues == 0, meaning rstat_rxf == 0, in which case budget_per_q is not utilized (as it has no meaning). Inititalize budget_per_q to 0 though to suppress this compile warning. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
