If the BLE radio stops responding before deinit is called the function can get stuck waiting for an event that is never received, particularly if the radio is external or on a separate core. This commit adds a timeout, similar to the timeout already used in the init function. Updated for nimble, btstack, esp32 and zephyr bindings.
