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]

1939 | int n, ret;

v5:
- Assign -ENOMEM to ret inside if block.
- Assign -EINVAL to ret inside case block.
v4:
- Move changelog below sign-off.
- Remove double-hyphens in commit description.
v3:
- Use prefix net.
- Remove so_txtime fix as default case calls error().
- Changelog before sign-off.
- Three dashes after sign-off
v2:
- Use subsystem name "net".
- Add fixes tags.
- Remove txtimestamp fix as default case calls error.
- Assign constant error string instead of NULL.

2.47.3Since it's now only to ovpn, better prefix, which matches other
patches in that directory, is "selftest/net/ovpn:"
Btw, review the posting rules. Leave 24 hours between reposts:
