When we change the crycb (or execution controls), we also have to make sure that the vSIE shadow datastructures properly consider the changed values before rerunning the vSIE. We can achieve that by simply using a VCPU request now. This has to be a synchronous request (== handled before entering the (v)SIE again). The request will make sure that the vSIE handler is left, and that the request will be processed (NOP), therefore forcing a reload of all vSIE data (including rebuilding the crycb) when re-entering the vSIE interception handler the next time.
