Fix the nova reconfigure in the multinode env
Fix the nova reconfigure in the multinode env

Checking the fix condition first in the when clause rather than the
dynamic condition. Otherwise it will raise issue, especially in
multinode env.

For example use

  when:
    - nova_console == 'novnc'
    - inventory_hostname in groups['nova-novncproxy']

rather than

  when:
    - inventory_hostname in groups['nova-novncproxy']
    - nova_console == 'novnc'

Because the nova-novncproxy groups may do not exist.
