A fix (bug #8942: SUBSTRING_INDEX in UPDATE causes internal loop).
sql/key.cc: A fix (bug #8942: SUBSTRING_INDEX in UPDATE causes internal loop). For "partial" key parts (e.g. key(a(20), ...) we create different key_part->field, see sql/table.cc; so we have to use the eq() function here to compare fields.
