[IA64-SGI]: fix `qw' might be used uninitialized warning

The compiler has no way of knowing whether nentries will be greater than 0, so
it was generating a warning that qw might be used uninitialized.  Fix it by
explicitly setting it to 0.  Cc'ing Brian in case he has an internal version
he'd like to keep in sync.
