Commit Message

In preparation for making the function static.

No functional change.

Fixes: 38620fc4e893 ('x86/xen: attempt to inflate the memory balloon on PVH')

Since this is a pre-requisite for a bugfix, I've tagged it with "Fixes:", not
sure if that's appropriate or there's some better tag to use.
