[CBRD-25288] Some values can not take the result in JDBC. (#5084)

http://jira.cubrid.org/browse/CBRD-25288

Since the FLOATING_PRECISION of the NUMERIC type is 15, an overflow error occurs if it exceeds 15 digits.
Executor automatically casts the host variables, so delete unnecessary casts in qo_reduce_equality_terms().
