Reset before initialisation of the SSD1306 when OLED reset pin is set

Browse Source 
If an OLED Reset pin has been selected using the PIN configuration, it makes sense to also send a reset signal to this pin before initialization of the display. The current value 0 doesn't send this signal, not even when a reset pin has been selected. Hence the change of value 0 into reset_pin >= 0. If no reset pin was set, the value of this variable is -1.
