nfsd: don't allow CLOSE to proceed until refcount on stateid drops
Once we remove client_mutex protection, it'll be possible to have an
in-flight operation using an openstateid when a CLOSE call comes in.
If that happens, we can't just put the sc_file reference and clear its
pointer without risking an oops.
Fix this by ensuring that v4.0 CLOSE operations wait for the refcount
to drop before proceeding to do so.
