location-functions.pl: Remove accidently keept 2nd DB init call.

The get_full_country_name() function had an accidenlty and not longer
required call of the DB init function.

This is a waste of memory and a known problem, especially on systems
with less than 1GB of RAM, where the application which uses libloc in
such a redundant way crashes.
