PM / Runtime: Generic resume shouldn't set RPM_ACTIVE unconditionally
The __pm_generic_resume() function changes the given device's runtime PM status to RPM_ACTIVE if its driver's callback returns 0, but it only should do that if the rumtime PM is enabled for the device. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
