[NET]: Messed multicast lists after dev_mc_sync/unsync

Commit a0a400d7

 ("[NET]: dev_mcast:
add multicast list synchronization helpers") from you introduced a new
field "da_synced" to struct dev_addr_list that is not properly
initialized to 0. So when any of the current users (8021q, macvlan,
mac80211) calls dev_mc_sync/unsync they mess the address list for both

The attached patch fixed it for me and avoid future problems.
