gpio-button-hotplug: use gpio_button_get_value() to initialize last_state.
TL-WR720N-v3 has a slider switch composed of 2 GPIO buttons which can be used to swtich between 3 positions. At leat 1 button is in pressed state in any of those positions. Initialize 'last_state' as 0 (released) will cause the device to automatically enter failsafe mode on every bootup. Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> SVN-Revision: 37643
