Subject: [03/21] NFSv4: Fix up the callers of nfs4_state_end_reclaim_reboot

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <Trond.Myklebust@...app.com>

commit e345e88a774875cec26e097ea3ff2dc40c4f9da2 upstream.

In practice, we need to ensure that we call nfs4_state_end_reclaim_reboot
in 2 cases:

 - If we lose the lease while we were reclaiming state
OR
 - After we're done with reboot recovery
