Similar to f6e0d19cc0 but
fixed in the header by making it a proper static inline
function (as some callers treats it as one, so do it
for all now for consistency).
Seen on Ubuntu 18.04 with
giving:
In file included from getaddrinfo-test.c:36:0:
getaddrinfo-test.c: In function ‘main’:
roken.h:110:24: error: statement with no effect [-Werror=unused-value]
#define rk_SOCK_INIT() 0
^
getaddrinfo-test.c:132:5: note: in expansion of macro ‘rk_SOCK_INIT’
rk_SOCK_INIT();
