Title: CRM-14317 fix for : while looking into this issue, found a DB: NAN field not found

I didn't replicated the actual issue but, had found this issue.

The issue : $minLatitude, $maxLatitude, $minLongitude, $maxLongitude the value stored in these variable is sometimes 'NAN' due to which, DB: Field not found mysql error is raised which result listing after search.

The fix: added is_nan during the clause building of geo_code where clause.
