net: fix building errors on powerpc when CONFIG_RETPOLINE is not set 

This commit fixes the errores reported when building for powerpc:

 ERROR: modpost: "ip6_dst_check" [vmlinux] is a static EXPORT_SYMBOL
 ERROR: modpost: "ipv4_dst_check" [vmlinux] is a static EXPORT_SYMBOL
 ERROR: modpost: "ipv4_mtu" [vmlinux] is a static EXPORT_SYMBOL
 ERROR: modpost: "ip6_mtu" [vmlinux] is a static EXPORT_SYMBOL

Fixes: f67fbeaebd ("net: use indirect call helpers for dst_mtu")
Fixes: bbd807dfbf ("net: indirect call helpers for ipv4/ipv6 dst_check functions")
