PM / Runtime: Fix error path in pm_runtime_force_resume()
commit 0ae3aeefabbeef26294e7a349b51f1c761d46c9f upstream.
As pm_runtime_set_active() may fail because the device's parent isn't
active, we can end up executing the ->runtime_resume() callback for the
device when it isn't allowed.
Fix this by invoking pm_runtime_set_active() before running the callback
and let's also deal with the error code.
Fixes: 37f204164dfb (PM: Add pm_runtime_suspend|resume_force functions)
