[PATCH] config: remove useless assignment

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

v1.7.9-8-g270a344 (config: stop using config_exclusive_filename) replaced
config_exclusive_filename with given_config_file.  In one case this
resulted in a self-assignment, which is reported by clang as a warning.
Remove the useless code.
