[PULL 2/3] ps2: Don't send key release event for Lang1, Lang2 keys

From: Ross Lagerwall <ross.lagerwall(a)citrix.com&gt; The scancodes for the Lang1 and Lang2 keys (i.e. Hangeul, Hanja) are special since they already have the 0x80 bit set which is commonly used to indicate a key release in AT set 1. Reportedly, real hardware does not send a key release scancode. So, skip sending a release for these keys. This ensures that Windows behaves correctly and interprets it as a single keypress rather than two consecutive keypresses.
