cli: volume status for tcp,rdma type volume display only tcp port

For tcp,rdma type voumes, there will be two ports, one for tcp
and one for rdma. But volume status command only display tcp port.
By this change, adding an extra column for rdma port and changing
the port to tcp port.

Eg:

>gluster volume status pathy

>For tcp,rdma type volume
