gcc-4.6: nfsd: fix initialized but not read warnings
Fixes at least one real minor bug: the nfs4 recovery dir sysctl
would not return its status properly.
Also I finished Al's 1e41568d7378d ("Take ima_path_check() in nfsd
past dentry_open() in nfsd_open()") commit, it moved the IMA
code, but left the old path initializer in there.
The rest is just dead code removed I think, although I was not
fully sure about the "is_borc" stuff. Some more review
would be still good.
Found by gcc 4.6's new warnings.
