[PATCH] PM / Domains: Only check for errors when calling dev_pm_get_subsys_data

[Heiko StÃbner]

Commit 1d5fcfec22 (PM / Domains: Add device domain data reference counter)
added a check for the return value of dev_pm_get_subsys_data.

But this function does not only return error codes but also "1" when a
new object has been created.

So, change the check to only catch real errors.
