[Qemu-devel] [PULL v2][ALSO STABLE] balloon: multiple fixes and cleanups

[Amit Shah]

Hello,

This new pull request carries the first 7 patches from the earlier
pull request that cleaned up balloon code and fixed a use-after-free
segfault on issuing 'balloon 0'.

This series adds 5 more patches that fix:
 - a memleak on unplug, 
 - migration after unplug,
 - negative balloon values by rejecting them

It also rejects creating multiple balloon devices.

Please pull.

Makes sense to pull these in for stable as well.

The following changes since commit c886edfb851c0c590d4e77f058f2ec8ed95ad1b5:
