Refactoring of code where ParserLocker is used.

[niport]

Currently the following code pattern is used several times into the FreescaleProxy class:

	ParserLocker lock = new ParserLocker();
		lock.setType(TypeMessage.PERMIT_JOIN);
		Status status = new Status();

		getListLocker().add(lock);

		sendData(frame);

		if (lock.getStatus().getCode() == ParserLocker.INVALID_ID)
			lock.getObjectLocker().poll(timeout, TimeUnit.MILLISECONDS);

		status = lock.getStatus();

		if (getListLocker().contains(lock)) {
			getListLocker().remove(lock);
		}

		if (status.getCode() == ParserLocker.INVALID_ID)
			throw new GatewayException("Timeout expired in Permit Join");
		else {
			if (status.getCode() != 0)
				throw new GatewayException(
						"Error on ZDP-Mgmt_Permit_Join.Request. Status code:" + status.getCode() + " Status Message: " + status.getMessage());
		}

It would be better to refactor the similar code in a method.
