winemenubuilder: Do not WINE_ERR in InvokeShellLinker if we are going to try again.

[Misha Koshelev]

When we are here, r is nonzero and bWait is TRUE, there are two possibilities:

1) r is nonzero b/c the parent process created the shortcut before its icon. In this case,
when we try again we will succeed, and the error here is misleading at best. (If we are tracing
+menubuilder, we will see WARN messages that inform us of the icon failure and a TRACE message that
we are waiting which should be sufficient).
2) r is nonzero for some other reason. In this case, we will fail again after the wait, and
there is no need to display the same error twice.
