Merge 2 if-blocks.

Second if-block had the same clause as first if-block, and it immediately
followed the first if-block.

Put add_latlon_atts line inside if (nRecordsOut == 0) block.
Coordinate variable attributes will only be added during initial creation of
output file, not if output file already exists.
