Fix memory leak (start enum)
Fix memory leak (start enum)

Enumeration loop added for object corruption.
Add missing free because of tee_svc_storage_set_enum
obj_id memory allocation (malloc) during enumeration loop.
Force obj_id to NULL in the enumation loop to skip freeing
at 'exit' label statement.
closes #494
