geo-rep: Fix issues with gfid conflict handling

1. MKDIR/RMDIR is recorded on all bricks. So if
   one brick succeeds creating it, other bricks
   should ignore it. But this was not happening.
   The fix rename of directories in hybrid crawl,
   was trying to rename the directory to itself
   and in the process crashing with ENOENT if the
   directory is removed.

2. If file is created, deleted and a directory is
   created with same name, it was failing to sync.
   Again the issue is around the fix for rename
   of directories in hybrid crawl. Fixed the same.

   If the same case was done with hardlink present
   for the file, it was failing. This patch fixes
   that too.
