The variable 'current_itr' is assigned to 0 before jumping to
'set_itr_now' but it has not been used after the jump. So, remove the
unneeded assignement.

Alternatively, you could just inline the max(...) into the switch and 
completely drop the current_itr definition.

But your solution probably does the job: it is a "No functional change" 
commit.
