[PATCH 0/5] Clean up open CLAIM_PREVIOUS code path

[Weston Andros Adamson <dros@netapp.com>]

My original patch was to just fix the NULL dereference, but Trond noticed
some other problems in _nfs4_opendata_reclaim_to_nfs4_state, so I went ahead
and fixed them.

I separated this into multiple patches for increased bisectability and made
sure the NULL dereference patch was first so that stable@ / distros can choose
to just fix the crash if they wish. 

I went a bit further than the issues Trond raised with the last patch, but I
think it's good for consistency and catching reference counting bugs as errors
and not BUG()s.
