[PATCH] nfs-utils: Add scratch directory for NFS upcall state storage

[Rich Dubielzig <rich.dubielzig@windriver.com>]

When the /var/lib/nfs/v4recovery directory is not present, NFSD cannot
record the upcall state and cannot end the 90-second grace period on
startup.  This is true even when NFS4 is not being served according to
nfsstat.
