virtio-scsi: fix disabled mode
Add two missing checks for s->dataplane_fenced. In one case, QEMU
would skip injecting an IRQ due to a write to an uninitialized
EventNotifier's file descriptor.
In the second case, the dataplane_disabled field was used by mistake;
in fact after fixing this occurrence it is completely unused.
