ice: Fix VF-VF direction matching in drop rule in switchdev
When adding a drop rule on a VF, rule direction is not being set, which
results in it always being set to ingress (ICE_ESWITCH_FLTR_INGRESS
equals 0). Because of this, drop rules added on port representors don't
match any packets.
To fix it, set rule direction in drop action to egress when netdev is a
port representor, otherwise set it to ingress.
Fixes: 0960a27bd479 ("ice: Add direction metadata")
