> When we are trying to change VF settings, it is possible for 2 race conditions
> to happen. One, when the VF is created but not yet enabled.
> Second, the VF is enabled but the vsi is still not created or not yet re-created
> in the VF reset flow.
> 
> This patch introduces a helper function to validate that the vf is enabled and
> that the vsi is set up. This patch also calls this function from other functions
> which could get into these race conditions.
> While we are poking around here, remove unnecessary parenthesis that
> checkpatch was complaining about.
