KVM: arm64: timers: Use a per-vcpu, per-timer accumulator for fractional ns
Instead of accumulating the fractional ns value generated every time
we compute a ns delta in a global variable, use a per-vcpu, per-timer
variable. This keeps the fractional ns local to the timer instead of
contributing to any odd, unrelated timer.
