i40e: fix accessing vsi->active_filters without holding lock

Browse source

Fix accessing vsi->active_filters without holding the mac_filter_hash_lock.
Move vsi->active_filters = 0 inside critical section and
move clear_bit(__I40E_VSI_OVERFLOW_PROMISC, vsi->state) after the critical
section to ensure the new filters from other threads can be added only after
filters cleaning in the critical section is finished.
