HID: magicmouse: scroll on entire surface, not just middle of mouse 

Previously, scroll events only occurred when the user moved a touch
along the middle of the touch surface. This is unintuitive for a normal
user who is not aware of this. The device has a uniform surface, so the
distinction is artificial. This change removes the touch area check for
a scroll event, which replicates the OS X behavior.
