[PATCH v5 15/24] virt/steal_monitor: Restore to active on module disable

[Shrikanth Hegde]

When the module is not in use, preferred CPUs must be same
as active CPUs.

Even if one disables the module during high steal time, it
still restores the preferred CPUs to be same as active CPUs
to keep disable path simple.
