[PATCH 2/3] NFS fix cb_sequence error processing

[andros@netapp.com]

From: Andy Adamson <andros@netapp.com>

Always assign the cb_process_state nfs_client pointer so a processing error
in cb_sequence after the nfs_client is found and referenced returns
a non-NULL cb_process_state nfs_client and the matching nfs_put_client in
nfs4_callback_compound dereferences the client.
