MDEV-29841 More descriptive text for ER_PARTITION_WRONG_TYPE

Browse Source 
For commands

  (1) alter table t1 add partition (partition p2);
  (2) alter table t1 add partition (partition px history);

It printed the same error message:

   Wrong partitioning type, expected type: `SYSTEM_TIME`

For (1) it is not clear from the syntax that we are trying to add
HASH partition. For (2) it is not clear that the table partitioning is
different than SYSTEM_TIME. Now it prints what type we are trying to
add to what type of partitioning.

Fixed warning unused function rename_field_in_list() for compilation
without partitioning.
