The previous patch added the nla_len check in rtnl_bridge_setlink, which
is the only caller for ndo_bridge_setlink handlers defined in low-level
driver codes. Hence, this patch cleanups the redundant checks in each
ndo_bridge_setlink handler function.

Please apply the fix discussed at the link:
https://lore.kernel.org/all/20230726075314.1059224-1-linma@zju.edu.cn/
first before this one.
