lib/stackdepot: kmsan: mark API outputs as initialized

KMSAN does not instrument stackdepot and may treat memory allocated by it
as uninitialized.  This is not a problem for KMSAN itself, because its
functions calling stackdepot API are also not instrumented.  But other
kernel features (e.g.  netdev tracker) may access stack depot from
instrumented code, which will lead to false positives, unless we
explicitly mark stackdepot outputs as initialized.
