Fix UnboundLocalError if 'access_key_ids' not supplied
Fix UnboundLocalError if 'access_key_ids' not supplied

'key_ids' is referenced before it is assigned, causing the module to fail with a UnboundLocalError instead of failing gracefully with a helpful error message.  This very small patch moves the assignment of 'key_ids' to before the variable is referenced.
