kvm/valgrind: don't mark memory as initialized

Browse Source 
since commit 7dda5dc82a ("migration: initialize RAM to zero") the
guest memory is defined zero. No need to call valgrind on guest memory.
This reverts commit 62fe83318d ("qemu: Use valgrind annotations to
mark kvm guest memory as defined") thus speeding up kvm start if
<includedir>/valgrind/valgrind.h is available.
