Calling SPI.setHwCs(true) twice disables hardware CS

[InvncibiltyCloak]

Hardware:

Board: ESP32 DevKitv1
Core Installation version: master
IDE name: Platform.io
Computer OS: Ubuntu

Description:

If you call SPI.setHwCs twice it causes hardware CS to be turned off due to a bad check in the else if.

This is easily fixed by changing the else if to be else if (!use && _use_hw_ss).

I found this while browsing master.

Sketch

#include <Arduino.h>

void setup() {
    SPI.begin()
    SPI.setHwCs(true);
    SPI.setHwCs(true);
    // CS pin does not get toggled now
}
