[Bluez PATCH] input/device: Notify failure if ctrl disconnect when waiting intr

From: Archie Pusaka <redacted>

On some rare occasions, the peer HID device might disconnect the ctrl
channel when we are trying to connect the intr channel. If this
happens, interrupt_connect_cb() will not be called by btio, and we
will be stuck in "connecting" state. Any future connection attempt to
the peer device will fail because of "busy".

This patch prevents that by checking if we need to report connection
failure when the ctrl channel is disconnected.
