PS/2: Actually mask off SysReq when it is released.

Browse Source 
The previous code was missing a "~" make it possible for someone to
press PrntScrn, and then later Alt+D to trigger KDL, which is obviously
not the desired behavior. SYS_REQ_KEY only triggers when Alt+SysReq
is pressed, so this was not as much of an issue without PrntScrn.
