nfsd: Add support for CLAIM_DELEG_PREV_FH to the NFSv4.1/4.2 Open
Commit b3d4c70dc60f added support for CLAIM_DELEG_CUR_FH to Open. While doing this, I noticed that CLAIM_DELEG_PREV_FH support could be added the same way. Although I am not aware of any extant NFSv4.1/4.2 client that uses this claim type, it seems prudent to add support for this variant of Open to the NFSv4.1/4.2 server. This patch does not affect mounts from extant NFSv4.1/4.2 clients, as far as I know. MFC after: 2 weeks
