Commit ee873fda3bec7c668407b837fc5519eb961fcd37 ("gianfar: Pack struct gfar_priv_grp into three cachelines") moved the irq number and names off into a separate struct and created accessors for them. However it was never tested with NET_POLL enabled, and so some conversions that were simply overlooked went undetected until now. Make the netpoll ones also use the gfar_irq() accessors.
