Bug #10039 MEMORY engine is reported as HEAP

Description:
Setting the storage_engine var to MEMORY succeeds, but what's reported isn't MEMORY, but still HEAP.

How to repeat:
mysql> SELECT VERSION();

| 5.0.4-beta-Max-log |
+--------------------+
1 row in set (0.00 sec)

mysql> SELECT @@global.storage_engine, @@local.storage_engine;
+-------------------------+--------------------------+
| @@global.storage_engine | @@session.storage_engine |
+-------------------------+--------------------------+
| MyISAM                  | MyISAM                   |
+-------------------------+--------------------------+

mysql> SET GLOBAL storage_engine = MEMORY;
Query OK, 0 rows affected (0.01 sec)

mysql> SET LOCAL storage_engine = MEMORY;
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT @@global.storage_engine, @@local.storage_engine;
+-------------------------+--------------------------+
| @@global.storage_engine | @@session.storage_engine |
+-------------------------+--------------------------+
| HEAP                    | HEAP                     |
+-------------------------+--------------------------+
1 row in set (0.00 sec)

Suggested fix:
Make it report MEMORY.
