ksmbd-tools: fix detection of multiple key-value definitions

[atheik]

Checking for multiple key-value definitions in add_group_key_value() does not work because `key' at lookup-time points to the last character in the key. Fix this by moving the check after `key' has its proper value extracted with g_strndup(). Also, make the associated logging message clearer.

Here is an example ksmbd.conf:

[test]
        comment = foo
        comment = bar

The key-value definition comment = bar should be ignored.
