If it is tcp only volume or rdma only volume,  it will show "49157,0" 
for the first one and
"TCP-49157 , RDMA-0" for the second or vice-versa , which is not an 
optimal, it is better
to show only available ports for that volume in the `port column`.

 From the user point of this gives better understanding of the rdma 
port.Although it may effect
current test scripts which parse the volume status command

May be ,it looks like weird one showing two brick process with same 
pid.But this change
is only for tcp,rdma volumes, in other cases it will continue with 
existing volume status
command. So it won't effect any current test scripts
