gpio-button-hotplug: gpio-keys: fix always missing first event
Commit afc056d7dc83 ("gpio-button-hotplug: support interrupt properties") changed the gpio-keys interrupt handling logic in a way, that it always misses first event, which causes issues with rc.button scripts, so this patch restores the previous behaviour.
