Bug description:
  [Impact]

   * Autofs leak file descriptors when reloaded (-HUP) and daemon may
  stop working on high # of shares/reloads.

  [Test Case]

  1. Configure a simple direct mount:

  # cat /etc/auto.master
  /-	/etc/auto.direct

  # cat /etc/auto.direct
  /nfs	server:/nfs

  2. Start the automounter and do NOT trigger the mount

  3. Replace /etc/auto.direct with:

  # cat /etc/auto.direct
  /nfs/1	server:/nfs
  /nfs/2	server:/nfs

  4. Reload:

  # kill -HUP $(pidof automount)

  >From now on, every reload will leak a file descriptor:

  # ls -la /proc/$(pidof automount)/fd | grep /nfs

  lr-x------ 1 root root 64 Aug 14 22:08 11 -> /nfs
  lr-x------ 1 root root 64 Aug 14 22:08 12 -> /nfs
  lr-x------ 1 root root 64 Aug 14 22:08 13 -> /nfs
  lr-x------ 1 root root 64 Aug 14 22:08 14 -> /nfs
  lr-x------ 1 root root 64 Aug 14 22:08 5 -> /nfs

  [Regression Potential]

   * based on upstream commit: autofs - version 5.0.7 - dd66c61a - file
  descriptor leak when reloading automount daemon. Tested with the same
  test case fix the error and not changing any other behavior.
