Update Servo.cpp

Changed AUTO_BED_LEVELING to AUTO_BED_COMPENSATION

Marlin/Servo.cpp

 uint8_t Servo::attach(int pin, int min, int max)
 {
   if(this->servoIndex < MAX_SERVOS ) {
-#if defined (ENABLE_AUTO_BED_LEVELING) && (PROBE_SERVO_DEACTIVATION_DELAY > 0)
+#if defined (ENABLE_AUTO_BED_COMPENSATION) && (PROBE_SERVO_DEACTIVATION_DELAY > 0)
     if (pin > 0) this->pin = pin; else pin = this->pin;
 #endif
     pinMode( pin, OUTPUT) ;                                   // set servo pin to output
