vzmigrate: don't exit 1 on success

An explicit exit 0 is required at the end of the script as
undo_lock calls undo_ssh_mux that can set $? to 1 due to
test statement returning false.

chkpnt(): add FIXME to add CRIU support

While vzctl supports CRIU, it does not do it for fine-grained
checkpoint/restore (i.e. vzctl suspend --suspend/--dump/--kill etc).

Add a comment about that.

vzlist: fix showing DISABLED

As pointed out in bug #3029, vzlist showing DISABLED=yes
if DISABLED=no is set in CT config.

As DISABLED is actually a tri-state value (yes/no/unset),
we need to check for YES value explicitly.
