[VLAN]: Don't copy ALLMULTI/PROMISC flags from underlying device
Changing these flags requires to use dev_set_allmulti/dev_set_promiscuity
or dev_change_flags. Setting it directly causes two unwanted effects:
- the next dev_change_flags call will notice a difference between
dev->gflags and the actual flags, enable promisc/allmulti
mode and incorrectly update dev->gflags
- this keeps the underlying device in promisc/allmulti mode until
the VLAN device is deleted
