net: unbreak CONFIG_RETPOLINE=n builds

The kbuild bot reported a build breakage with CONFIG_RETPOLINE=n
due to commit aaa5d90b ("net: use indirect call wrappers at
GRO network layer").
I screwed the wrapper implementation for such config.
Fix the issue properly ignoring the builtin symbols arguments,
when retpoline is not enabled.
