Currently if an fopen fails the error exit path is via code that checks if fp is not null and closes the file, however, fp is null so this check and close is redundant. Since the only use of the err exit label is on the fopen check, remove it and replace the code with a simple return of errno. Also remove variable rc since it's no longer required.
