net/mlx5: Allow/disallow LAG according to pre-req only
Remove the lag forbid/allow functions, change the lag prereq check to
run in the do-bond logic, so every change in the prereq state will
cause LAG to be disabled/enabled accordingly after the next do-bond run.
Add lag update function, so every component which changes the prereq
state and want the LAG to re-calc the conditions can call the update
function.
