Subject: [PATCH 1/2 v2 net-next] net_failover: Use netdev_features_t instead
 of u32

The features mask needs to be a netdev_features_t (u64) because a u32
is not big enough.

Fixes: cfc80d9a1163 ("net: Introduce net_failover driver")

v2: In the original patch, I thought that the & should be | and I
    introduced a bug.
