Peter Fang 28b50463c9 hv: vm: properly reset pCPUs with LAPIC PT enabled during VM shutdown/reset ...

When a VM is configured with LAPIC PT mode and its vCPU is in x2APIC
mode, the corresponding pCPU needs to be reset during VM shutdown/reset
as its physical LAPIC was used by its guest.

This commit fixes an issue where this reset never happens.
is_lapic_pt_enabled() needs to be called before reset_vcpu() to be able
to correctly reflect a vCPU's APIC mode.

A vCPU with LAPIC PT mode but in xAPIC mode does not require such reset,
since its physical LAPIC was not touched by its guest directly.

v2 -> v3:
- refine edge case detection logic

v1 -> v2:
- use a separate function to return the bitmap of LAPIC PT enabled pCPUs
