ospf6d: Fix crash when '[no] ipv6 ospf6 advertise prefix-list' is in startup-config

Browse source 
* ospf6_interface.c: When '[no] ipv6 ospf6 advertise prefix-list'
  appears in the startup configuration for ospf6d, a crash occurs,
  because ospf6d attempts to schedule LSAs when the 'oi->area'
  structure has not yet been initialized.

  Now, when the command above is issued (either in the startup
  configuration or at runtime), ospf6d will only schedule LSAs if
  the 'oi->area' structure has been initalized. A similar test is
  already used when handling the commands 'ipv6 ospf6 priority'
  and 'ipv6 ospf6 cost'.
