[PATCH] kvm-userspace: Fix -no-kvm-irqchip

Commit fc94d163d1e3424199166cf50449e03447400579 broke -no-kvm-irqchip.
This fixes the issue by restoring the logic of
kvm_update_interrupt_request /wrt IRQ injection from the IO thread.

[However, I did not yet get the need for all the additional tests in
that function.]
