Sagi added this with a commit log of:

"
nvmet: Make cntlid globally unique
    
We usually log the cntlid which is confusing in case
we have multiple subsystems each with it's own cntlid ida.
Instead make cntlid ida globally unique and log the initial
association.
"

which seems reasonable.  If you have a reason for not making it unique,
it needs to be stated here so we can weight it against the original
reason for making the ids globally unique.
