This series fixes the following crash:
$ qemu-system-ppc64 -M pseries $(for ((x=0;x<128;x++)); do \
echo -n " -prom-env "$(for ((y=0;y<1024;y++)); do echo -n x ; done) ; \
done) # this requires ~128 Kib
malloc(): corrupted top size
Aborted (core dumped)
This also affects g3beige and mac99 machine types, and probably some
sparc/sparc64 machine types as well, but I prefer to leave the fixing
to knowledgeable people.
v2: - error out instead of increasing the partition size for the
sake of migration (Laurent)
- Cc'ing John Snow who reported the issue

nvram: Add dry_run argument to chrp_nvram_create_system_partition()
