[PATCH] nfsd4: support CLAIM_DELEGATE_CUR 



Add OPEN claim type NFS4_OPEN_CLAIM_DELEGATE_CUR to nfsd4_open().

A delegation stateid and a name are provided.  OPEN with O_CREAT is not legal
with this claim type; otherwise, use the NFS4_OPEN_CLAIM_NULL code path to
lookup the filename to be opened.
