Issue

• nfsclient resource doesn't inherit a 'mountpoint' attribute from parent fs resource if the nfsexport resource is not a direct parent of nfsclient resource

• following configuration fails with error when attempting to start the cluster service

  <resources>
    <nfsclient name="jim" target="jim.example.com" options="rw,no_root_squash"/>
    <nfsexport name="exports"/>
  </resources>
  ...
  <nfsexport ref="exports">
    <fs name="1" mountpoint="/mnt/foo" device="/dev/sdb1" fsid="12344">
      <nfsclient ref="jim"/>
    </fs>
  </nfsexport>
  
  
    [nfsclient] No export path specified.
