When built with '-Doptimization=1', GCC produces a compiler warning:
In file included from ../lib/isc/include/isc/lib.h:44,
from ../tests/dns/qp_test.c:26:
../tests/dns/qp_test.c: In function ‘check_predecessors_withchain’:
../lib/isc/include/isc/util.h:182:33: error: ‘ival’ may be used uninitialized [-Werror=maybe-uninitialized]

This is apparently a false positive, because the qpiter_prev_with_name()
function, when returning ISC_R_SUCCESS, sets the 'ival' (passed to
it by a pointer), and the caller checks that the return value is
ISC_R_SUCCESS before using 'ival'.
Initialize the 'ival' variable to 0 anyway to avoid the build error.
