Subject: [PATCH] RxRPC: Fix v1 keys

From: Anton Blanchard <anton@....ibm.com>

commit 339412841d7 (RxRPC: Allow key payloads to be passed in XDR form)
broke klog for me. I notice the v1 key struct had a kif_version field
added:

-struct rxkad_key {
-       u16     security_index;         /* RxRPC header security index */
-       u16     ticket_len;             /* length of ticket[] */
-       u32     expiry;                 /* time at which expires */
-       u32     kvno;                   /* key version number */
-       u8      session_key[8];         /* DES session key */
-       u8      ticket[0];              /* the encrypted ticket */
-};

+struct rxrpc_key_data_v1 {
+       u32             kif_version;            /* 1 */
+       u16             security_index;
+       u16             ticket_length;
+       u32             expiry;                 /* time_t */
+       u32             kvno;
+       u8              session_key[8];
+       u8              ticket[0];
+};

However the code in rxrpc_instantiate strips it away:

	data += sizeof(kver);
	datalen -= sizeof(kver);

Removing kif_version fixes my problem.
