> There exists a bug in which the driver is unable to exit overflow promiscuous
> mode after having added "too many" mac filters.  It is expected that after
> triggering overflow promiscuous, removing the failed/extra filters should
> then disable overflow promiscuous mode.
> 
> The bug exists because we were intentionally skipping the sync_vsi_filter
> path in cases where we were removing failed filters since they shouldn't
> have been added to the firmware in the first place, however we still need to
> go through the sync_vsi_filter code path to determine whether or not it is ok
> to exit overflow promiscuous mode.  This patch fixes the bug by making sure
> we go through the sync_vsi_filter path in cases of failed filters.
