Filipe Manana c48792c6ee btrfs: do not log new dentries when logging that a new name exists 
When logging a new name for an inode, due to a link or rename operation,
we don't need to log all new dentries of the parent directories and their
subdirectories. We only want to log the names of the inode and that any
new parent directories exist. So in this case don't trigger logging of
the new dentries, that is only need when doing an explicit fsync on a
directory or on a file which requires logging its parent directories.

This avoids unnecessary work and reduces contention on the extent buffers
of a log tree.

This patch is part of a patch set comprised of the following patches:

  btrfs: check if a log tree exists at inode_logged()
  btrfs: remove no longer needed checks for NULL log context
  btrfs: do not log new dentries when logging that a new name exists
  btrfs: always update the logged transaction when logging new names
  btrfs: avoid expensive search when dropping inode items from log
  btrfs: add helper to truncate inode items when logging inode
  btrfs: avoid expensive search when truncating inode items from the log
  btrfs: avoid search for logged i_size when logging inode if possible
  btrfs: avoid attempt to drop extents when logging inode for the first time
  btrfs: do not commit delayed inode when logging a file in full sync mode

This is patch 3/10 and test results are listed in the change log of the
last patch in the set.
