NFSv4.x: fix lock recovery during delegation recall
[ Upstream commit 44f411c353bf6d98d5a34f8f1b8605d43b2e50b8 ]
Running "./nfstest_delegation --runtest recall26" uncovers that
client doesn't recover the lock when we have an appending open,
where the initial open got a write delegation.
Instead of checking for the passed in open context against
the file lock's open context. Check that the state is the same.
