Subject: [PATCH 4.14 149/173] NFSv4: try lease recovery on NFS4ERR_EXPIRED

From: Robert Milkowski <rmilkowski@...il.com>

commit 924491f2e476f7234d722b24171a4daff61bbe13 upstream.

Currently, if an nfs server returns NFS4ERR_EXPIRED to open(),
we return EIO to applications without even trying to recover.

Fixes: 272289a3df72 ("NFSv4: nfs4_do_handle_exception() handle revoke/expiry of a single stateid")
