Subject: [PATCH 5.15 038/244] NFSv4.1: Handle NFS4ERR_DELAY replies to OP_SEQUENCE correctly

From: Trond Myklebust <trond.myklebust@...merspace.com>

commit 7ccafd4b2b9f34e6d8185f796f151c47424e273e upstream.

Don't assume that the NFS4ERR_DELAY means that the server is processing
this slot id.

Fixes: 3453d5708b33 ("NFSv4.1: Avoid false retries when RPC calls are interrupted")
