Revert "Make libvirt safe again"

This reverts commit 53a64cb871eb6889571a09e69c787681ba83e41c.

This commit was based on a wrong assumption that the default port
is not used during live migration.
In fact, while libvirt can use another range of port during
live migration for copying disks and memory,
the main control channel still happens over connection
to the port 16509 (default in /etc/libvirt/libvirtd.conf).

Blocking this port manifests as 

Live Migration failure: operation failed:
Failed to connect to remote libvirt URI
qemu+tcp://cmp02/system: unable to connect
to server at 'cmp02:16509': Connection timed out

error in nova-compute log when attempting to perform a live migration.
