When a runtime resume callback returns an error, rpm_callback() sets power.runtime_error on the device. This causes all subsequent calls to rpm_resume() to return -EINVAL immediately at the top of the function without invoking the callback again, making the failure permanent until runtime PM is explicitly re-initialized. Unlike suspend failures, resume failures should be retryable. If a device's resume callback fails, there is no reason to permanently block future resume attempts on that device and all of its consumers. Fix this by moving the power.runtime_error assignment out of the generic rpm_callback() and into rpm_suspend() at its fail label, where suspend callback failures are handled. Resume callback failures now return the error to the caller but leave power.runtime_error clear, allowing the next resume attempt to invoke the callback normally.
