Alex Williamson 154304cd6e postcopy: Synchronize usage of the balloon inhibitor ...

While the qemu_balloon_inhibit() interface appears rather general purpose,
postcopy uses it in a last-caller-wins approach with no guarantee of balanced
inhibits and de-inhibits.  Wrap postcopy's usage of the inhibitor to give it
one vote overall, using the same last-caller-wins approach as previously
implemented at the balloon level.

Fixes: 01ccbec7bdf6 ("balloon: Allow multiple inhibit users")
