ospfd: Respect loopback's cost that is set and set loopback costs to 0
When setting an loopback's cost, set the value to 0, unless the operator has assigned a value for the loopback's cost. RFC states: If the state of the interface is Loopback, add a Type 3 link (stub network) as long as this is not an interface to an unnumbered point-to-point network. The Link ID should be set to the IP interface address, the Link Data set to the mask 0xffffffff (indicating a host route), and the cost set to 0. FRR is going to allow this to be overridden if the operator specifically sets a value too. Fixes: #13472 Signed-off-by: Donald Sharp <sharpd@nvidia.com> (cherry picked from commit dd2bc4fb406cc9284d35ef623ebb8838cb158bc8)
