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

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 f5ea16137a3fa2858620dc9084466491c128535f.
