KVM: arm/arm64: Remove arch timer workqueue
The use of a work queue in the hrtimer expire function for the bg_timer is a leftover from the time when we would inject interrupts when the bg_timer expired. Since we are no longer doing that, we can instead call kvm_vcpu_wake_up() directly from the hrtimer function and remove all workqueue functionality from the arch timer code.
