NFS client updates for Linux 4.10

Highlights include:

Stable bugfixes:
- Fix a pnfs deadlock between read resends and layoutreturn
- Don't invalidate the layout stateid while a layout return is outstanding
- Don't schedule a layoutreturn if the layout stateid is marked as invalid
- On a pNFS error, do not send LAYOUTGET until the LAYOUTRETURN is complete
- SUNRPC: fix refcounting problems with auth_gss messages.

Features:
- Add client support for the NFSv4 umask attribute.
- NFSv4: Correct support for flock() stateids.
- Add a LAYOUTRETURN operation to CLOSE and DELEGRETURN when return-on-close
is specified
- Allow the pNFS/flexfiles layoutstat information to piggyback on LAYOUTRETURN
- Optimise away redundant GETATTR calls when doing state recovery and/or
when not required by cache revalidation rules or close-to-open cache
consistency.
- Attribute cache improvements
- RPC/RDMA support for SG_GAP devices

Bugfixes:
- NFS: Fix performance regressions in readdir
- pNFS/flexfiles: Fix a deadlock on LAYOUTGET
- NFSv4: Add missing nfs_put_lock_context()
- NFSv4.1: Fix regression in callback retry handling
- Fix false positive NFSv4.0 trunking detection.
- pNFS/flexfiles: Only send layoutstats updates for mirrors that were updated
- Various layout stateid related bugfixes
- RPC/RDMA bugfixes
