Bug#57890: Assertion failed: next_insert_id == 0 

           with on duplicate key update

There was a missed corner case in the partitioning
handler, which caused the next_insert_id to be changed
in the second level handlers (i.e the hander of a partition),
which caused this debug assertion.

The solution was to always ensure that only the partitioning
level generates auto_increment values, since if it was done
within a partition, it may fail to match the partition
function.
