[ovs-dev] [PATCH ] debian: Fix bringup seq for OVSPort type of vlan.

When the OVSPort is a vlan interface there is a sequencing issue when we try
to bring up the OVSBridge.
Consider the following configuration in /etc/network/interfaces

allow-ovs br-foo
iface br-foo inet static
    ovs_type OVSBridge
    ovs_ports eth1.2052

# Interface eth1.2052
allow-br-foo eth1.2052
iface eth1.2052 inet manual
    ovs_type OVSPort
    ovs_bridge br-foo
    bridge_name br-foo

If we run 'service openvswitch start' then we'd get the following errors.
2015-10-08T00:05:45.279Z|00019|bridge|WARN|could not open network device eth1.2052 (No such device)

Due to the current sequence the script /etc/network/if-pre-up.d/openvswitch
with IF_OVS_TYPE=OVSPort is run prior to the script
/etc/network.if-pre-up.d/vlan which brings up the vlan interface eth1.2052.

The fix is to order the openvswitch script to run after the other interface
scripts in /etc/network/if-pre-up.d/
