Hi all.

After my patch

    commit 58110f0acb1a33e2bc60a2f1b26d2690a92e8a14

        migration: split common postcopy out of ram postcopy

test 181 becomes broken. Sorry for that.

Actually, test 181 itself should be fixed, so, here is a fix.
The problem was noted by Kevin, and it touches also some problems
with image locking, which I don't see with my older kernel, so,
please check is this patch fixes all problems.
