ice: use ice_is_vf_trusted helper function

The ice_vc_cfg_promiscuous_mode_msg function directly checks
ICE_VIRTCHNL_VF_CAP_PRIVILEGE, instead of using the existing helper
function ice_is_vf_trusted. Switch this to use the helper function so
that all trusted checks are consistent. This aids in any potential
future refactor by ensuring consistent code.
