ospfd: Fixing "show ip ospf neighbour <nbrid>" command

ospfd: Fixing "show ip ospf neighbour <nbrid>" command

Description:
	"show ip ospf neighbour [nbrid] [json]" is expected to give brief output
	of the specific neighbour. But it gives the detailed output without
	the detail keyword.
	"show ip ospf neighbour [nbrid] [deatil] [json]" command is failed to
	fetch the ecpected o/p. Corrected it.

	Ex o/p:
	frr(config-if)# do show ip ospf  neighbor

	Neighbor ID     Pri State           Up Time         Dead Time Address         Interface                        RXmtL RqstL DBsmL
