Sean Christopherson f47491d7f3 KVM: x86/mmu: Handle "default" period when selectively waking kthread 
Account for the '0' being a default, "let KVM choose" period, when
determining whether or not the recovery worker needs to be awakened in
response to userspace reducing the period.  Failure to do so results in
the worker not being awakened properly, e.g. when changing the period
from '0' to any small-ish value.
