[PATCH 3.4 15/39] SUNRPC: dont map EKEYEXPIRED to EACCES in call_refreshresult

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Adamson <andros@xxxxxxxxxx>

commit f1ff0c27fd9987c59d707cd1a6b6c1fc3ae0a250 upstream.

The NFS layer needs to know when a key has expired.
This change also returns -EKEYEXPIRED to the application, and the informative
"Key has expired" error message is displayed. The user then knows that
credential renewal is required.
