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 5d3dbbeaf5
removed the NULL checks, it didn't add a check for -ENOENT.
