[PATCH iwl-next v2] ice: call netif_keep_dst() once when entering switchdev mode

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

From: Marcin Szycik <marcin.szycik@intel.com>

netif_keep_dst() only needs to be called once for the uplink VSI, not
once for each port representor.  Move it from ice_eswitch_setup_repr()
to ice_eswitch_enable_switchdev().

Fixes: defd52455aee ("ice: do Tx through PF netdev in slow-path")

v1 -> v2:
 - Verified Fixes: tag via bisect - defd52455aee introduced the redundant
   per-repr call to netif_keep_dst(uplink_vsi->netdev) by changing the
   target netdev to the uplink VSI inside the per-representor setup
   function. Before that commit, each call was on a distinct repr->netdev
   so no Fixes: predating it applies.
