[PULL for-6.2 1/2] pmu: fix pmu vmstate subsection list

[Cédric Le Goater]

From: Laurent Vivier <lviv...@redhat.com>

The subsection is not closed by a NULL marker so this can trigger
a segfault when the pmu vmstate is saved.

This can be easily shown with:

  $ ./qemu-system-ppc64  -dump-vmstate vmstate.json
  Segmentation fault (core dumped)
