HID: intel-ish-hid: Fix potential race condition
Although unlikely but it is possible that when a connect or disconnect request is issued to the firmware, before the response comes, user terminates the client session. In this case when the response is arrived there is no matching client instance in the list of currently active clients. In this case, don't issue call to wake up a waiting client.
