ANDROID: cpufreq: scmi: Fix scmi_limit_notify_cb handling

Current SCMI limits notification handling relies solely on a vendor hook
to handle changes in frequency constraints. If the hook is not registered
or fails, updated min/max limits are not propagated.

Restore freq_qos_update_request() in scmi_limit_notify_cb to ensure Freq
QoS is updated when the vendor hook is absent or fails.
