net: inline rollback_registered_many()
commit 0cbe1e57a7b93517100b0eb63d8e445cfbeb630c upstream.
Similar to the change for rollback_registered() -
rollback_registered_many() was a part of unregister_netdevice_many()
minus the net_set_todo(), which is no longer needed.
Functionally this patch moves the list_empty() check back after:
BUG_ON(dev_boot_phase);
ASSERT_RTNL();
but I can't find any reason why that would be an issue.
