Chen Gang 30d1e0e806 virt/kvm/assigned-dev.c: Set 'dev->irq_source_id' to '-1' after free it ...

As a generic function, deassign_guest_irq() assumes it can be called
even if assign_guest_irq() is not be called successfully (which can be
triggered by ioctl from user mode, indirectly).

So for assign_guest_irq() failure process, need set 'dev->irq_source_id'
to -1 after free 'dev->irq_source_id', or deassign_guest_irq() may free
it again.
