With very small change to test script we can trigger softlockup due to
bogus assignment of 'p' (policy to be examined) on restart.
Previously the two to-be-merged nodes had same address/prefixlength pair,
so no erase/reinsert was necessary, we only had to append the list from
node a to b.
If prefix lengths are different, the node has to be deleted and re-inserted
into the tree, with the updated prefix length. This was broken; due to
bogus update to 'p' this loops forever.
Add a 'restart' label and use that instead.
While at it, don't perform the unneeded reinserts of the policies that
are already sorted into the 'new' node.
A previous patch in this series made xfrm_policy_inexact_list_reinsert()
use the relative position indicator to sort policies according to age in
case priorities are identical.
