netfilter: nf_iterate: fix incorrect RCU usage
As noticed by Eric, nf_iterate doesn't use RCU correctly by
accessing the prev pointer of a RCU protected list element when
a verdict of NF_REPEAT is issued.
Fix by jumping backwards to the hook invocation directly instead
of loading the previous list element before continuing the list
iteration.
