zebra: Allow ns delete to happen after under/over flow checks

Browse Source 
Allow the ns deletion event to happen *after* the data validity
checks.

Please note this probably still leaves a weird hole if we receive
multiple namespace events ( as the for loop implies ).  We will
stop handling anything after a namespace deletion notification.
