ospfd: Fix MI-OSPF configuraton clis

Multi-Instance OSPF configuration CLI would fail because
first client return error upon seeing qobj_index being 0.
With new marco generate new error code to return from each
instance (vtysh client) and if the command is intended for given
instance, its qobj_index would be nonzero and process the command
and push correct ospf context. Other instance would return the error.
On vtysh end, check all instance return an error log a message to a
file.

Testing Done:
Verfied various MI-OSPF configuration CLI with multi instances.
