    Fix dhcp_release lease race condition
    
    There is a possible race condition when delete or updating fixed_ips
    on ports where an instance could renew its ip address again after
    dhcp_release has already been executed. To fix this, the order of
    reload_allocation and release_lease need to be switched. This way an
    instance will not be able to renew it's ip address after it is
    removed from the host file.
