Wang Hui 927633a6d2 stm class: Fix module init return on allocation failure 
In stm_heartbeat_init(): return value gets reset after the first
iteration by stm_source_register_device(), so allocation failures
after that will, after a clean up, return success. Fix that.

Fixes: 1192918530 ("stm class: Add heartbeat stm source device")
