lockd: fix lockd shutdown race
As reported by David Jeffery: "a signal was sent to lockd while lockd was shutting down from a request to stop nfs. The signal causes lockd to call restart_grace() which puts the lockd_net structure on the grace list. If this signal is received at the wrong time, it will occur after lockd_down_net() has called locks_end_grace() but before lockd_down_net() stops the lockd thread. This leads to lockd putting the lockd_net structure back on the grace list, then exiting without anything removing it from the list." So, perform the final locks_end_grace() from the the lockd thread; this ensures it's serialized with respect to restart_grace(). Reported-by: David Jeffery <djeffery@redhat.com> Signed-off-by: J.
