[PATCH] nfsdclnts: fix display of stateids where the kernel doesn't provide the superblock

[Frank Sorenson <sorenson@redhat.com>]

If the stateid's file can't be found, the kernel will skip printing
the superblock and filename in the 'states' procfile.  When this
happens, nfsdclnts crashes trying to reference the non-existent
superblock key while getting the inode.

Fix this by setting the inode field to 'N/A' when the superblock
isn't present, as is done with other fields which may be missing.
