client/metadata: fix crasher caused by AllowStale = false (#16549)
Fixes #16517

Given a 3 Server cluster with at least 1 Client connected to Follower 1:

If a NodeMeta.{Apply,Read} for the Client request is received by
Follower 1 with `AllowStale = false` the Follower will forward the
request to the Leader.

The Leader, not being connected to the target Client, will forward the
RPC to Follower 1.

Follower 1, seeing AllowStale=false, will forward the request to the
Leader.

The Leader, not being connected to... well hoppefully you get the
picture: an infinite loop occurs.
