kasan: memset free track in qlink_free
Instead of only zeroing out the stack depot handle when evicting the free stack trace in qlink_free, zero out the whole track. Do this just to produce a similar effect for alloc and free meta. The other fields of the free track besides the stack trace handle are considered invalid at this point anyway, so no harm in zeroing them out.
