hv: ptdev: move softirq_dev_entry_list from vm structure to per_cpu region

Browse Source 
Using per_cpu list to record ptdev interrupts is more reasonable than
recording them per-vm. It makes dispatching such interrupts more easier
as we now do it in softirq which happens following interrupt context of
each pcpu.
