ospfd: fix area removal at interface level
Areas created via interface command are not being deleted when
executing the command `no ip ospf area x`
With the following configuration:
!
interface eth1
ip address 10.0.12.2/24
ip ospf area 0.0.0.100
!
router ospf
!
r2# sh ip ospf
OSPF Routing Process, Router ID: 2.2.2.2
Supports only single TOS (TOS0) routes
....
Number of opaque AS LSA 0. Checksum Sum 0x00000000
Number of areas attached to this router: 1 <--- ***
Area ID: 0.0.0.100 <--- ***
Shortcutting mode: Default, S-bit consensus: ok
Number of interfaces in this area: Total: 1, Active: 1
Number of fully adjacent neighbors in this area: 0
Area has no authentication
Number of full virtual adjacencies going through this area: 0
SPF algorithm executed 1 times
Number of LSA 1
Number of router LSA 1. Checksum Sum 0x0000f3d4
Number of network LSA 0. Checksum Sum 0x00000000
Number of summary LSA 0. Checksum Sum 0x00000000
Number of ASBR summary LSA 0. Checksum Sum 0x00000000
Number of NSSA LSA 0. Checksum Sum 0x00000000
Number of opaque link LSA 0. Checksum Sum 0x00000000
Number of opaque area LSA 0. Checksum Sum 0x00000000
However when removing the area from the interface, the command
above displays the same information
r2# conf t
r2(config)# int eth1
r2(config-if)# no ip ospf area 0.0.0.100
r2(config-if)# exit
r2(config)# exit
r2# sh ip ospf

r2# sh run

!
router ospf
!
end
This PR removes the area when executing `no ip ospf area` command
