CPU pinning requires the KVM hypervisor to start in the paused state, in
order to retrieve information, and immediately unpauses it.

This does not play well with live migration, as the unpausing was done
before the migration started and so the receiving kvm process left the
migrated instance in the stopped status.

This patch fixes this behavior, by not launching the KVM process in
stopped state while on the receiving side of a migration.

Also, the stopping is now done outside _ExecuteCpuAffinity.

Commit 41e1e79e introduced a feature in which when wait_for_sync is not
set, DRBD sync is paused during the OS installation.

Doing so, however, broke OS creation's error handling: the result value
from the instance_os_add RPC call was overwritten by the one of the
blockdev_pause_resume_sync call before there was a chance for it to
be raised and thus masking possible errors in the OS creation.

Note that the wipe method, from which the pause technique was inspired,
does not suffer from this bug.
