HID: Send Close event to upper layers during reconnection

This patch sends close event callback to upper layers, so that UI
is updated of correct state of HID connection when connection
between hid host and hid device drops for some reason and host is
attempting reconnection. Without this patch, upper layers gives
false update of connection still present when actually no connection
exists between hid devices. Connection state was only getting updated
if reconnection attempt was also failing.
