Fix functions that return undefined values. These issues were caught by
running clang using LLVM=1 option.
Clang warnings are as follows:
ovpn-cli.c:1587:6: warning: variable 'ret' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
1587 | if (!sock) {
| ^~~~~
ovpn-cli.c:1635:9: note: uninitialized use occurs here
1635 | return ret;
| ^~~
ovpn-cli.c:1587:2: note: remove the 'if' if its condition is always false
1587 | if (!sock) {
| ^~~~~~~~~~~~
1588 | fprintf(stderr, "cannot allocate netlink socket\n");
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1589 | goto err_free;
| ~~~~~~~~~~~~~~
1590 | }
| ~
ovpn-cli.c:1584:15: note: initialize the variable 'ret' to silence this warning
1584 | int mcid, ret;
| ^
| = 0
ovpn-cli.c:2107:7: warning: variable 'ret' is used uninitialized whenever switch case is taken [-Wsometimes-uninitialized]
2107 | case CMD_INVALID:
| ^~~~~~~~~~~
ovpn-cli.c:2111:9: note: uninitialized use occurs here
2111 | return ret;
| ^~~
ovpn-cli.c:1939:12: note: initialize the variable 'ret' to silence this warning
1939 | int n, ret;
