Mark Fasheh afc798599f scoutfs: invalidate cache when we free locks ...

We weren't invalidating our cache before freeing locks due to memory
pressure. This would cause stale data on the node which originally held
the lock. Fix this by firing a callback from dlmglue before we free a
lock from the system. On the scoutfs side, the callback is wired to
call our invalidate function. This will ensure that the right data and
metadata hit disk before another node is allowed to acquire that lock.
