libnm: minor cleanup releasing setting from NMConnection

Browse source 
There are two callers that are concerned with disconnecting/releasing a
setting:

 - _setting_release_hfr() (formerly _setting_release())

 - _nm_connection_add_setting() for the @s_old setting

Compared to one caller that connects/adds a setting (_nm_connection_add_setting()).

Refactor the two callers to use the same helper function
(_setting_release()) so that the implementation of how to release a
setting is at one place.

This patch was originally done when adding another signal to NMSetting.
That did not happen (yet), but the refactoring still makes sense.
