geolocation with LOC dns record is broken

When the geolocation function tries to use LOC records from DNS, it checks for degree_latitude and degree_longitude being set in the output, and it converts degrees minutes seconds to signed decimal degrees to set location_lat and location_lon. Because the output from the dns library is already converted to decimal degrees with a different name than is being checked for, the output isn't found. The attached patch uses the output of the library to set location_lat and location_lon.
