You don't need to change the code.

At Mediawiki:Common.css set:
ns-0 #p-logo a {
 background-image: url(http://example.com/logo-main-namespace.png)
!important;
}
ns-1 #p-logo a {
 background-image: url(http://example.com/logo-talk-namespace.png)
!important;
}
and so on.

$wgLogo will be the default logo for those namespaces which you don't
override.
