unset params in --ps --embedded

Details

    Description

      here's a simple test case:

      select ?+1

      in normal mtr mode it fails with a syntax error. In --ps mode it fails because no values was supplied for a parameter. But in --ps --embedded it crashes, because the value was still not supplied, MYSQL_BIND is not initialized, but embedded doesn't know it, and accesses uninitialized structure.
