xfrm: Make set-mark default behavior backward compatible
Fixes 9b42c1f179a6, which changed the default route lookup behavior for
tunnel mode SAs in the outbound direction to use the skb mark, whereas
previously mark=0 was used if the output mark was unspecified. In
mark-based routing schemes such as Android’s, this change in default
behavior causes routing loops or lookup failures.
This patch restores the default behavior of using a 0 mark while still
incorporating the skb mark if the SET_MARK (and SET_MARK_MASK) is
specified.
Tested with additions to Android's kernel unit test suite:

Fixes: 9b42c1f179a6 ("xfrm: Extend the output_mark to support input direction and masking")
