The NFSv4 renew daemon is shared between all active super blocks that refer
to a particular NFS server, so it is wrong to be shutting it down in
nfs4_kill_super every time a super block is destroyed.

This patch therefore kills nfs4_renewd_prepare_shutdown altogether, and
leaves it up to nfs4_shutdown_client() to also shut down the renew daemon
by means of the existing call to nfs4_kill_renewd().
