ppc/xive2: Add undelivered group interrupt to backlog
When a group interrupt cannot be delivered, we need to:
- increment the backlog counter for the group in the NVG table
(if the END is configured to keep a backlog).
- start a broadcast operation to set the LSMFB field on matching CPUs
which can't take the interrupt now because they're running at too
high a priority.
[npiggin: squash in fixes from milesg]
[milesg: only load the NVP if the END is !ignore]
[milesg: always broadcast backlog, not only when there are precluded VPs]
