J. Bruce Fields 49e7372063 nfsd: fh_update should error out in unexpected cases 
The reporter saw a NULL dereference when a filesystem's ->mknod returned
success but left the dentry negative, and then nfsd tried to dereference
d_inode (in this case because the CREATE was followed by a GETATTR in
the same nfsv4 compound).

fh_update already checks for this and another broken case, but for some
reason it returns success and leaves nfsd trying to soldier on.  If it
failed we'd avoid the crash.  There's only so much we can do with a
buggy filesystem, but it's easy enough to bail out here, so let's do
that.
