Richard Sharpe 9d36cdb650 Handling negative dentries in a CI file system.

For a Case Insensitive file system we must avoid creating negative
entries in the dentry cache. We must also pass the FIGNORECASE into
zfs_lookup so that special files are handled correctly.

We must also prevent negative dentries from being created when files are
unlinked.

Tested by running fsstress from LTP (10 loops, 10 processes, 10,000 ops.)

Also tested with printks (now removed) to ensure that lookups come to
zpl_lookup when negative should not exist.

Tests:
1.   ls Some-file.txt; touch some-file.txt; ls Some-file.txt
  and ensure no errors.

2.   touch Some-file.txt; rm some-file.txt; ls Some-file.txt
  and ensure that the last ls shows log messages showing the lookup
  went all the way to zpl_lookup.

Thanks to tuxoko for helping me get this correct.
