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.
