Description of problem:
This is related to bug 123342. The patch for that bug added two identical guards
in activateFOSMonitors and sendLvsArps:

+	      if (!config->failoverServices[j].isActive)
+		continue;
+

This causes us to skip inactive services so that we do not incorrectly think
their VIPs are already active if they are used by other services.

A similar problem exists in deactivateLvs:

  /* deactivate the interfaces */
  for (i = 0; i < config->numVirtServers; i++)
    { 

      if (config->virtServers[i].failover_service)
        { 
          piranha_log (flags, (char *) "Warning; skipping failover service");
          continue;             /* This should not be possbile anymore */
        } 
  
      for (j = 0; j < i; j++)
        { 
          if (!memcmp (&config->virtServers[i].virtualAddress,
                       &config->virtServers[j].virtualAddress,
                       sizeof (config->virtServers[i].virtualAddress)))
            break;
        }

      if (j == i)
        disableInterface (config->virtServers[i].virtualDevice, flags);
    }

In the inner loop, we will incorrectly break and avoid deactivating the
interface in the case that virtServers[j] is inactive but its virtualAddress
matches the other service.

This needs another check to see if virtServers[j] is inactive and continue if
that is the case.

This problem causes the VIP to remain active on the LVS router that is shutting
down, leading to it being active on both the primary and backup router in the
case of a failover.

Version-Release number of selected component (if applicable):
piranha-0.8.3-1

How reproducible:
100%

Steps to Reproduce:
1. Create an LVS configuration with at least two virtual servers sharing a
single VIP
2. Disable the first service by setting "active = 0" in lvs.cf
3. Start the pulse service on both primary & backup routers
4. VIP should start correctly on primary
5. Stop pulse on the primary router
6. Confirm that VIP has been failed over to the backup router

Actual results:
The VIP is active on both primary and backup LVS routers

Expected results:
The VIP is active only on one router at a time (the backup router in this example).

Additional info:
The same effect is seen when failing back to the primary by re-starting pulse on
the primary router then stopping pulse on the backup router.
