In your code nrf_drv_gpiote_is_init() will return an error if the GPIOTE is already initialized and your application will hang or reset in APP_ERROR_CHECK(). If you do it like this:

uint32_t err_code;
if(!nrf_drv_gpiote_is_init())
{
    err_code = nrf_drv_gpiote_init();
}

as is suggested here you will simply skip the initialization if it is already done before.
