Summary: Joystick POV can only go left and right when using
                    joydev interface

I've been having trouble getting a very annoying joystick (Saitek X45) work in
Wine. For a start, it needs calibration so I am forced to use joydev and not
evdev. Problem was, I couldn't get the POV to be registered when pushing it up
or down (though left and right works without issue). I tracked down the problem
to a missing 'else' in calculate_pov(). Patch attached.

Enjoy....dev! :)
