4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lihong Yang <[email protected]>

commit eab077aa84331afbda071a213925d4cdbca58941 upstream.

In __i40e_del_filter function, the flag __I40E_MACVLAN_SYNC_PENDING for
the PF state is wrongly set for the VSI. Deleting any of the MAC filters
has caused the incorrect syncing for the PF. Fix it by setting this state
flag to the intended PF.
