[ Upstream commit 789e1e10f214c00ca18fc6610824c5b9876ba5f2 ]
Currently, we shut down the filecache before trying to clean up the stateids that depend on it. This leads to the kernel trying to free an nfsd_file twice, and a refcount overput on the nf_mark.
Change the shutdown procedure to tear down all of the stateids prior to shutting down the filecache.
