Find the first NULL value in index-suffix values tuple
SYNOPSIS
ha_find_null()
keyseg Array of keyparts for key suffix
a Key suffix value tuple
DESCRIPTION
Find the first NULL value in index-suffix values tuple.
TODO Consider optimizing this fuction or its use so we don't search for
NULL values in completely NOT NULL index suffixes.
RETURN
First key part that has NULL as value in values tuple, or the last key part
(with keyseg->type==HA_TYPE_END) if values tuple doesn't contain NULLs.
