Lately tsc page was implemented but filled with empty
values. This patch setup tsc page scale and offset based
on vcpu tsc, tsc_khz and HV_X64_MSR_TIME_REF_COUNT value.
The valid tsc page drops HV_X64_MSR_TIME_REF_COUNT msr
reads count to
m_run
appropriately.

Hello!
Yes, we can use KVM_EXIT_REG_IO/MSR_IO for Hyper-V SynIC MSRS's changes
and can even use only one MSR value . So union inside struct
kvm_hyperv_exit is excessive.
But we still need Vcpu exit to handle VMBus hypercalls by QEMU to
emulate VM
The function stimer_stop() is called in one place
so remove the function and replace it's call by function
content.

Split stimer_expiration() into two parts - timer expiration message
sending and timer restart/cleanup based on timer state(config).
This also fixes a bug where a one-shot timer message whose delivery
failed once would get lost for good.
