Mauricio Faria de Oliveira 45680967ee ocfs2: ratelimit the 'max lookup times reached' notice 
Running stress-ng on ocfs2 completely fills the kernel log with 'max
lookup times reached, filesystem may have nested directories.'

Let's ratelimit this message as done with others in the code.

Test-case:

  # mkfs.ocfs2 --mount local $DEV
  # mount $DEV $MNT
  # cd $MNT

  # dmesg -C
  # stress-ng --dirdeep 1 --dirdeep-ops 1000
  # dmesg | grep -c 'max lookup times reached'

Before:

  # dmesg -C
  # stress-ng --dirdeep 1 --dirdeep-ops 1000
  ...
  stress-ng: info:  [11116] successful run completed in 3.03s

  # dmesg | grep -c 'max lookup times reached'
  967

After:

  # dmesg -C
  # stress-ng --dirdeep 1 --dirdeep-ops 1000
  ...
  stress-ng: info:  [739] successful run completed in 0.96s

  # dmesg | grep -c 'max lookup times reached'
  10

  # dmesg
  [  259.086086] ocfs2_check_if_ancestor: 1990 callbacks suppressed
  [  259.086092] (stress-ng-dirde,740,1):ocfs2_check_if_ancestor:1091 max lookup times reached, filesystem may have nested directories, src inode: 18007, dest inode: 17940.
  ...
