Enric Balletbo i Serra b53b012805 PM / devfreq: Fix static checker warning in try_then_request_governor 
The patch 23c7b54ca1: "PM / devfreq: Fix devfreq_add_device() when
drivers are built as modules." leads to the following static checker
warning:

    drivers/devfreq/devfreq.c:1043 governor_store()
    warn: 'governor' can also be NULL

The reason is that the try_then_request_governor() function returns both
error pointers and NULL. It should just return error pointers, so fix
this by returning a ERR_PTR to the error intead of returning NULL.

Fixes: 23c7b54ca1 ("PM / devfreq: Fix devfreq_add_device() when drivers are built as modules.")
