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.
