SubjectRxRPC: Fix v1 keys

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.
