David Cermak d11e5c8683 modbus: Exit server task gracefully to correctly cleanup lwip internals ...

Current lwip implementation does not support deleting a task which is
actively waiting on `select()` or `poll()` API.
Therefore we have to make sure that `select()` exits to deallocate its internal
callback before deleting the task. This is achieved by a shutdown
semaphore which informs the client once the `select()` exitted.
