net: napi: Make napi_defer_hard_irqs per-NAPI
Add defer_hard_irqs to napi_struct in preparation for per-NAPI settings. The existing sysfs parameter is respected; writes to sysfs will write to all NAPI structs for the device and the net_device defer_hard_irq field. Reads from sysfs show the net_device field. The ability to set defer_hard_irqs on specific NAPI instances will be added in a later commit, via netdev-genl.
