[PATCH v1 1/2] NFSD: Delay adding new entries to LRU

[Chuck Lever <cel@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

Neil Brown observes:
> I would not include RC_INPROG entries in the lru at all - they are
> always ignored, and will be added when they are switched to
> RCU_DONE.

I also removed a stale comment.
