IntelFrameworkModule/Ps2Kb: ReadKeyStrokeEx always return key state
Today's implementation only return key state when there is a key.
But when user doesn't press any key, the key state cannot be
returned.
The patch changes the ReadKeyStrokeEx() to always return the
key state even there is no key pressed.
