SYNOPSIS
ha_find_null()

DESCRIPTION
Find the first NULL value in index-suffix values tuple.

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.
