4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <trond.myklebust@primarydata.com>
commit b88fa69eaa8649f11828158c7b65c4bcd886ebd5 upstream.
Ensure that the client conforms to the normative behaviour described in RFC5661 Section 12.7.2: "If a client believes its lease has expired, it MUST NOT send I/O to the storage device until it has validated its lease."
So ensure that we wait for the lease to be validated before using the layout.
