MINOR: config: Don't dump keywords if argument is NULL

Browse Source 
Helper functions are used to dump bind, server or filter keywords. These
functions are used to report errors during the configuration parsing. To have a
coherent API, these functions are now prepared to handle a null pointer as
argument. If so, no action is performed and functions immediately return.

This patch should fix the issue #631. It is not a bug. There is no reason to
backport it.
