net: fec: tx processing does not call XDP APIs if budget is 0
According to the clarification [1] in the latest napi.rst, the tx processing cannot call any XDP (or page pool) APIs if the "budget" is 0. Because NAPI is called with the budget of 0 (such as netpoll) indicates we may be in an IRQ context, however, we cannot use the page pool from IRQ context.
