[PATCH bpf-next] net: remove duplicate INDIRECT_CALLABLE_DECLARE of udp[6]_ehashfn

[PATCH bpf-next] net: remove duplicate INDIRECT_CALLABLE_DECLARE of udp[6]_ehashfn

[Lorenz Bauer]

There are already INDIRECT_CALLABLE_DECLARE in the hashtable
headers, no need to declare them again.

Fixes: 0f495f761722 ("net: remove duplicate reuseport_lookup functions")
Suggested-by: Martin Lau <martin.lau@linux.dev>
Signed-off-by: Lorenz Bauer <lmb@isovalent.com>
---
As pointed out by Martin there are some duplicate macro invocations
in my recent SO_REUSEPORT support for sk_assign patchset.

Remove the declarations in the .c files.
