* components/gardena_bluetooth: Improve avaliability reliability
The available() function incorrectly returns false even though the device
is accessible.
The last_update_success property should correctly indicate if the device
isn't contactable, so we don't need to call async_address_present().
This is confirmed by seeing that no other users are calling
async_address_present() in the available() function.
This commit removes the call to async_address_present() to help fix the
sensor being unavailable when using a ESPHome BLE proxy.
