NFSD: Avoid using rqstp->rq_vers in nfsd_set_fh_dentry()
Currently, fh_verify() makes some daring assumptions about which version of file handle the caller wants, based on the things it can find in the passed-in rqstp. The about-to-be-introduced LOCALIO use case sometimes has no svc_rqst context, so this logic won't work in that case. Instead, examine the passed-in file handle. It's .max_size field should carry information to allow nfsd_set_fh_dentry() to initialize the file handle appropriately. The file handle used by lockd and the one created by write_filehandle never need any of the version-specific fields (which affect things like write and getattr requests and pre/post attributes).
