CMGS ca58685f4c vmm: call notify_guest_clock_paused for Hyper-V guests
Previously, KVM_KVMCLOCK_CTRL was skipped when kvm_hyperv=on because
Windows does not use pvclock directly. However, KVM internally uses
pvclock data structures as the basis for computing the Hyper-V
Reference TSC page parameters. Not calling KVM_KVMCLOCK_CTRL means
there is no mechanism to signal time discontinuity to Windows guests
after pause/resume, contributing to multi-minute hangs.

Remove the kvm_hyperv guard so all guests receive the clock-paused
notification.
