Subject: [PATCH v2 iwl-next] ice: use ice_down_up() where applicable

ice_change_mtu() is currently using a separate ice_down() and ice_up()
calls to reflect changed MTU. ice_down_up() serves this purpose, so do
the refactoring here.

v1->v2:
- avoid setting ICE_VSI_DOWN bit as ice_down_up() covers it [Przemek]
