lkl: lib: remove dead code

Remove dead code caught by LLVM. Fixes the following warnings:

lib/net.c:44:20: warning: unused function 'set_sockaddr' [-Wunused-function]
static inline void set_sockaddr(struct lkl_sockaddr_in *sin, unsigned int addr,

lib/config.c:431:16: warning: variable 'bytes_read' set but not used [-Wunused-but-set-variable]
        int ret = -1, bytes_read = 0;
