ice: Remove deprecated ice_lag_move_new_vf_nodes() call

Moving the code to handle the LAG part of a VF reset to helper
functions deprecated the function ice_lag_move_new_vf_nodes().
The cleanup missed a call to this function in the error path of
ice_vc_cfg_qs_msg().

In the case that would end in the error path, a NULL pointer would
be encountered due to the empty list of netdevs for members of the
aggregate.

Remove the unnecessary call to ice_lag_move_new_vf_nodes(), and since
this is the only call to this function, remove the function as well.

Fixes: 351d8d8ab6af ("ice: breakout common LAG code into helpers")
