net: adjust napi_consume_skb to handle non-NAPI callers
Some drivers reuse/share code paths that free SKBs between NAPI and non-NAPI calls. Adjust napi_consume_skb to handle this use-case. Before, calls from netpoll (w/ IRQs disabled) was handled and indicated with a budget zero indication. Use the same zero indication to handle calls not originating from NAPI/softirq. Simply handled by using dev_consume_skb_any(). This adds an extra branch+call for the netpoll case (checking in_irq() + irqs_disabled()), but that is okay as this is a slowpath.
