zebra: Delay the usage of one variable until need

Browse Source 
In the loop, local variable `ip` is always set even if the check condition
is not satisfied.

Avoid the redundant set, move this set exactly after the check condition is
satisfied. Set `ip` only if the check condition is met, otherwise needn't.
