PM / devfreq: Propagate error from devfreq_add_device() 

commit d1bf2d3072 upstream.

Propagate the error of devfreq_add_device() in devm_devfreq_add_device()
rather than statically returning ENOMEM. This makes it slightly faster
to pinpoint the cause of a returned error.

Fixes: 8cd84092d3 ("PM / devfreq: Add resource-managed function for devfreq device")
