Linux Ethernet Bridging - Nov 2020 - [Bridge] [PATCH net] net: bridge: add missing counters to ndo_get_stats64 callback

In br_forward.c and br_input.c fields dev->stats.tx_dropped and
dev->stats.multicast are populated, but they are ignored in
ndo_get_stats64.

Fixes: 28172739f0a2 ("net: fix 64 bit counters on 32 bit arches")

Patch will not apply cleanly on kernel versions that don't have
dev_fetch_sw_netstats() yet.

Looks straightforward enough, I'll backport manually.

Applied, thanks!
