Change subject: Inline ret definition in dco_linux.c

Patch Set 1: Code-Review-2
(1 comment)
Patchset:
PS1:
cppcheck doesn't understand the `NLA_PUT()` macros, which on failure `goto
nla_put_failure`, which is:
```
nla_put_failure:
nlmsg_free(nl_msg);
return ret;
```
So the -EMSGSIZE initial value _is_ read.
So this patch would add undefined behavior to every path it touches.
