Pull up revision 1.32 (requested by lukem in ticket #392):
Move the test for "more strict reverse lookup handling" to the correct
location so that an uninitialized `in' won't be used if net_i == BYADDR.
Detected with gcc -Wuninitialized, confirmed by diffing against BIND 4.9.11.
(The bug was introduced in rev 1.26.  Hi Itojun! :)
