socket: fix unused-function warning
When procfs is disabled, the fdinfo code causes a harmless
warning:
net/socket.c:1000:13: error: 'sock_show_fdinfo' defined but not used [-Werror=unused-function]
static void sock_show_fdinfo(struct seq_file *m, struct file *f)
Move the function definition up so we can use a single #ifdef
around it.
Fixes: b4653342b151 ("net: Allow to show socket-specific information in /proc/[pid]/fdinfo/[fd]")
