Currently, it's possible for the
cancel_requestedflag to be cleared without the vcpu being cancelled. This can lead to a call tokill()being lost. Consider the following thread interleaving:kill()which setscancel_requestedto truecancel_requestedto false.This PR fixes it by only clearing the flag when the vcpu is actually interrupted.
