team: refine IFF_XMIT_DST_RELEASE capability
Cloned patch of Eric Dumazet for bonding.
Some workloads greatly benefit of IFF_XMIT_DST_RELEASE capability
on output net device, avoiding dirtying dst refcount.
team currently disables IFF_XMIT_DST_RELEASE unconditionally.
If all ports have the IFF_XMIT_DST_RELEASE bit set, then
team dev can also have it in its priv_flags.
