KVM: x86: Account fastpath-only VM-Exits in vCPU stats
commit 8b703a49 upstream. Increment vcpu->stat.exits when handling a fastpath VM-Exit without going through any part of the "slow" path. Not bumping the exits stat can result in wildly misleading exit counts, e.g. if the primary reason the guest is exiting is to program the TSC deadline timer.
