KVM: x86: Account fastpath-only VM-Exits in vCPU stats
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.
