So far, the DIAG 500 hypervisor call was only setting -EINVAL in R2 when a guest tried to call this function with an illegal subcode. This patch now changes the behavior so that a specification exception is thrown instead, since this is the common behavior of other DIAG functions (and other CPU instructions) when being called with illegal parameters.
