packet: Do not leak dev refcounts on error exit
[ Upstream commit d972f3dce8d161e2142da0ab1ef25df00e2f21a9 ]
'dev' is non NULL when the addr_len check triggers so it must goto a label
that does the dev_put otherwise dev will have a leaked refcount.
This bug causes the ib_ipoib module to become unloadable when using
systemd-network as it triggers this check on InfiniBand links.
Fixes: 99137b7888f4 ("packet: validate address length")
