[PATCH net] net: wangxun: use net_prefetch to simplify logic

Use net_prefetch to remove #ifdef and simplify prefetch logic. This
follows the pattern introduced in a previous commit f468f21b7af0 ("net:
Take common prefetch code structure into a function"), which replaced
the same logic in all existing drivers at that time.

Fixes: 3c47e8ae113a ("net: libwx: Support to receive packets in NAPI")
