since commit 7dda5dc82a77 ("migration: initialize RAM to zero") the
guest memory is defined zero. No need to call valgrind on guest memory.
This reverts commit 62fe83318d2f ("qemu: Use valgrind annotations to
mark kvm guest memory as defined") thus speeding up kvm start if
<includedir>/valgrind/valgrind.h is available.
