nhop: hash ifnet pointer instead of if_index
Yet another problem created by VIMAGE/if_vmove/epair design that
relocates ifnet between vnets and changes if_index. Since if_index
changes, nhop hash values also changes, unlink_nhop() isn't able to
find entry in hash and leaks the nhop. Since nhop references ifnet,
the latter is also leaked. As result running network tests leaks
memory on every single test that creates vnet jail.
That sounds like something (new) is done in wrong sequence for these
cases. Plastering around that sounds wrong as it simply hides the
real problem.
