Dan Carpenter e0827388ba stm class: Fix a double free in stm_register_device() 
ANBZ: #12940

commit 3df463865b upstream.

The put_device(&stm->dev) call will trigger stm_device_release() which
frees "stm" so the vfree(stm) on the next line is a double free.

Fixes: 389b6699a2 ("stm class: Fix stm device initialization order")
