gpio-button-hotplug: fix wrong initial seen value
Currently the generated event contains wrong seen value, when the button
is pressed for the first time:
rmmod gpio_button_hotplug; modprobe gpio_button_hotplug
[ pressing the wps key immediately after modprobe ]
gpio-keys: create event, name=wps, seen=1088, pressed=1
So this patch adds a check for this corner case and makes seen=0 if the
button is pressed for the first time.
