Fix broken error check for iconv_open() result in iso_to_utf8()

The variable 'i2utf8' was misspelled as the function name 'iso_to_utf8'
in the error check. This would cause the error condition to always be false,
preventing proper detection of iconv_open() failures.

Luckily ISO-8859-1 to UTF-8 should always be available.
