Subject: [PATCH] netdev: Reset ipv4 flags during bundle creation on interfamily ipsec

This patch resets the ipv4-related flags in the new flow as their
content will otherwise depend on the bits of the ipv6 addresses the
struct was previously used for. For example, fl4_tos might have
RTO_ONLINK set, which usually prevents the right route from being
found.

This bit was chopped off the larger patch dealing with the problems
related to creating the bundles for inter-family tranformations.
