net/cdc_ncm: Fix multicast RX support for CDC NCM devices with ZLP
ZLP for DisplayLink ethernet devices was enabled in 6.0:
266c0190aee3 ("net/cdc_ncm: Enable ZLP for DisplayLink ethernet devices").
The related driver_info should be the "same as cdc_ncm_info, but with
FLAG_SEND_ZLP". However, set_rx_mode that enables handling multicast
traffic was missing in the new cdc_ncm_zlp_info.
usbnet_cdc_update_filter rx mode was introduced in linux 5.9 with:
e10dcb1b6ba7 ("net: cdc_ncm: hook into set_rx_mode to admit multicast
traffic")
Without this hook, multicast, and then IPv6 SLAAC, is broken.
Fixes: 266c0190aee3 ("net/cdc_ncm: Enable ZLP for DisplayLink ethernet devices")
