Subject: [PATCH net-next v2 04/15] ice: refactor ice_vf_lib to make functions static

From: Jan Sokolowski <jan.sokolowski@...el.com>

As following methods are not used outside ice_vf_lib,
they can be made static:
ice_vf_rebuild_host_vlan_cfg
ice_vf_rebuild_host_tx_rate_cfg
ice_vf_set_host_trust_cfg
ice_vf_rebuild_host_mac_cfg
ice_vf_rebuild_aggregator_node_cfg
ice_vf_rebuild_host_cfg
ice_set_vf_state_qs_dis
ice_vf_set_initialized

In order to achieve that, the order in which these
were defined was reorganized.
