Revert "net: Reset secmark when scrubbing packet"

[ Upstream commit 4c0ee414e877b899f7fc80aafb98d9425c02797f ]

This patch reverts commit b8fb4e0648a2ab3734140342002f68fb0c7d1602
because the secmark must be preserved even when a packet crosses
namespace boundaries.  The reason is that security labels apply to
the system as a whole and is not per-namespace.
