[PATCH net-next] net: always declare __sock_wfree() and tcp_wfree()

[PATCH net-next] net: always declare __sock_wfree() and tcp_wfree()

[Eric Dumazet]

Even if guarded by IS_ENABLED(CONFIG_INET) compilers need to know
what __sock_wfree() and tcp_wfree() are:

   include/net/sock.h:1861:63: note: each undeclared identifier is reported only once for each function it appears in
   include/net/sock.h:1862:63: error: 'tcp_wfree' undeclared (first use in this function); did you mean 'sock_wfree'?
    1862 |                (IS_ENABLED(CONFIG_INET) && skb->destructor == tcp_wfree);

Fixes: f0de88303d5e ("net: make is_skb_wmem() available to modules")
