namei: make set_root_rcu() return void
The only caller that cares about its return value can just as easily pick it from nd->root_seq itself. We used to just calculate it and return to caller, but these days we are storing it in nd->root_seq in all cases. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
