[ Upstream commit 1b6599f741a4525ca761ecde46e5885ff1e6ba58 ]
In the error path after calling dev_set_name(), the device
name is leaked. To fix this, calling dev_set_name() before
device_register(), and call put_device() if it returns error.
All the resources is released in powercap_release(), so it
can return from powercap_register_zone() directly.
