Revert "NFSv4: Retry LOCK on OLD_STATEID during delegation return"

Browse Source 
[ Upstream commit 5b4a82a0724af1dfd1320826e0266117b6a57fbd ]

Olga Kornievskaia reports that this patch breaks NFSv4.0 state recovery.
It also introduces additional complexity in the error paths for cases not
related to the original problem.  Let's revert it for now, and address the
original problem in another manner.

This reverts commit f5ea16137a.
