devices: virtio_pci_device: restore fix

Restore right now tries to restore interrupts at all times. If the
device was not previously activated, the interrupt will always be null
which will cause the restore to always fail. Add a check to see if the
device was previously activated before restoring the interrupt.

BUG=N/A
Test=presubmit
