David Hildenbrand 8fb48de871 powerpc/pseries/cmm: call balloon_devinfo_init() also without CONFIG_BALLOON_COMPACTION ...

commit fc6bcf9ac4 upstream.

Patch series "powerpc/pseries/cmm: two smaller fixes".

Two smaller fixes identified while doing a bigger rework.


This patch (of 2):

We always have to initialize the balloon_dev_info, even when compaction is
not configured in: otherwise the containing list and the lock are left
uninitialized.

Likely not many such configs exist in practice, but let's CC stable to
be sure.

This was found by code inspection.
