J. Bruce Fields 960fbf77d8 nfsd4: fix NULL dereference in nfsd/clients display code 
[ Upstream commit 9affa435817711861d774f5626c393c80f16d044 ]

We hold the cl_lock here, and that's enough to keep stateid's from going
away, but it's not enough to prevent the files they point to from going
away.  Take fi_lock and a reference and check for NULL, as we do in
other code.
