NFSv4: Don't allow a cached open with a revoked delegation
[ Upstream commit be3df3dd4c70ee020587a943a31b98a0fb4b6424 ]
If the delegation is marked as being revoked, we must not use it
for cached opens.
Fixes: 869f9dfa4d6d ("NFSv4: Fix races between nfs_remove_bad_delegation() and delegation return")
