Shuo A Liu 9a15ea82ee hv: pause all other vCPUs in same VM when do wbinvd emulation
Invalidate cache by scanning and flushing the whole guest memory is
inefficient which might cause long execution time for WBINVD emulation.
A long execution in hypervisor might cause a vCPU stuck phenomenon what
impact Windows Guest booting.

This patch introduce a workaround method that pausing all other vCPUs in
the same VM when do wbinvd emulation.
