net/bonding: fix unicast packets filtering

[ upstream commit 0ec2344 ]

By default, the 802.3ad code enables promisc mode on all slaves.
To avoid all packets going to the application (unless the application
asked for promiscuous mode), all frames are supposed to be filtered in
the rx burst handler.

However the incriminated commit broke this because non pure ethernet
frames (basically any unicast Ether()/IP() packet) are not filtered
anymore.

Fixes: 71b7b37 ("net/bonding: use ptype flags for LACP Rx filtering")
