Subject: [PATCH] net: add missing prefetch.h include

Fixes build errors on s390 and probably other archs as well:

  In file included from net/ipv4/ip_forward.c:32:0:
  include/net/udp.h: In function 'udp_csum_outgoing':
  include/net/udp.h:141:2: error: implicit declaration of function 'prefetch'
