Lookup for HID device bug in HID-FLASH cli

[TheKikGen]

The HID search loop in the CLI code has a bug.

                           BUG HERE -----------------v
if((cur_dev->vendor_id == VID)&&(cur_dev->product_id = PID))

should be == instead of =

if((cur_dev->vendor_id == VID)&&(cur_dev->product_id == PID)){

original code :

 while (cur_dev) { //Search for valid HID Bootloader USB devices
      if((cur_dev->vendor_id == VID)&&(cur_dev->product_id = PID)){
        valid_hid_devices++;
        if(cur_dev->release_number < FIRMWARE_VER){ //The STM32 board has firmware lower than 3.00
          printf("\nError - Please update the firmware to the latest version (v3.00+)");
          goto exit;
        }
      }
      cur_dev = cur_dev->next;
    }
