[DIRMINA-1123] Receive buffer size is never set for NIO acceptor

Description

Acceptor window size can't be increased beyond OS defaults.

It seems the receive buffer size is properly set for org.apache.mina.transport.socket.nio.NioSocketConnector, but it is not set at all for org.apache.mina.transport.socket.nio.NioSocketAcceptor before socket is bound.

org.apache.mina.core.polling.AbstractPollingIoAcceptor.Acceptor#registerHandles comment states that receive buffer size should be initialised, but then org.apache.mina.transport.socket.nio.NioSocketAcceptor#open does not do it.,
