Joe Hattori ccdec7ea9a powercap: call put_device() on an error path in powercap_register_control_type() 
[ Upstream commit 93c66fbc28 ]

powercap_register_control_type() calls device_register(), but does not
release the refcount of the device when it fails.

Call put_device() before returning an error to balance the refcount.

Since the kfree(control_type) will be done by powercap_release(), remove
the lines in powercap_register_control_type() before returning the error.

This bug was found by an experimental verifier that I am developing.
