3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Weston Andros Adamson <dros@netapp.com>
commit d2bfda2e7aa036f90ccea610a657064b1e267913 upstream.
Cached opens have already been handled by _nfs4_opendata_reclaim_to_nfs4_state and can safely skip being reprocessed, but must still call update_open_stateid to make sure that all active fmodes are recovered.
