After commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically,
it need be freed in error path.
Current all protocols used in pnp_register_protocol() is static, they
don't have a release function(), so just call kfree_const() to free
the name.
