Kuniyuki Iwashima 60bfd345cc bridge: Handle error of rtnl_register_module(). 
[ Upstream commit cba5e43b0b757734b1e79f624d93a71435e31136 ]

Since introduced, br_vlan_rtnl_init() has been ignoring the returned
value of rtnl_register_module(), which could fail silently.

Handling the error allows users to view a module as an all-or-nothing
thing in terms of the rtnetlink functionality.  This prevents syzkaller
from reporting spurious errors from its tests, where OOM often occurs
and module is automatically loaded.

Let's handle the errors by rtnl_register_many().

Fixes: 8dcea18708 ("net: bridge: vlan: add rtm definitions and dump support")
Fixes: f26b296585 ("net: bridge: vlan: add new rtm message support")
Fixes: adb3ce9bcb ("net: bridge: vlan: add del rtm message support")
