Subject: Fixing lease renewal

commit 8faaa6d5d48b201527e0451296d9e71d23afb362 upstream.

Commit c9fdeb28 removed a 'continue' after checking if the lease needs
to be renewed. However, if client hasn't moved, the code falls down to
starting reboot recovery erroneously (ie., sends open reclaim and gets
back stale_clientid error) before recovering from getting stale_clientid
on the renew operation.
