knfsd: Fixed problem with NFS exporting directories which are mounted on.
Recent changes in NFSd cause a directory which is mounted-on to not appear properly when the filesystem containing it is exported. *exp_get* now returns -ENOENT rather than NULL and when commit 5d3dbbeaf56d0365ac6b5c0a0da0bd31cc4781e1 removed the NULL checks, it didn't add a check for -ENOENT.
