NFSv4: Avoid unnecessary scans of filesystems for delayed delegations
[ Upstream commit e767b59e29b8327d25edde65efc743f479f30d0a ]
The amount of looping through the list of delegations is occasionally
leading to soft lockups. If the state manager was asked to manage the
delayed return of delegations, then only scan those filesystems
containing delegations that were marked as being delayed.
Fixes: be20037725d1 ("NFSv4: Fix delegation return in cases where we have to retry")
