ospfd: Display all ospf peers with show ip ospf neighbor detail all

Problem reported that no peers are displayed when the command "show
ip ospf neighbor detail all" is entered.  Determined that the problem
was actually that the function only displayed NBMA peers, and since
we rarely (if ever) define NBMA peers, nothing is normally displayed.
Changed the code to display both NBMA and non-NBMA peers, in both the
up and down state.  Manual testing attached to the jira ticket.
