Filipe Manana a35788ddf8 btrfs: don't log conflicting inode if it's a dir moved in the current transaction 
commit 266273eaf4 upstream.

We can't log a conflicting inode if it's a directory and it was moved
from one parent directory to another parent directory in the current
transaction, as this can result an attempt to have a directory with
two hard links during log replay, one for the old parent directory and
another for the new parent directory.

The following scenario triggers that issue:

1) We have directories "dir1" and "dir2" created in a past transaction.
   Directory "dir1" has inode A as its parent directory;

2) We move "dir1" to some other directory;

3) We create a file with the name "dir1" in directory inode A;

4) We fsync the new file. This results in logging the inode of the new file
   and the inode for the directory "dir1" that was previously moved in the
   current transaction. So the log tree has the INODE_REF item for the
   new location of "dir1";

5) We move the new file to some other directory. This results in updating
   the log tree to included the new INODE_REF for the new location of the
   file and removes the INODE_REF for the old location. This happens
   during the rename when we call btrfs_log_new_name();

6) We fsync the file, and that persists the log tree changes done in the
   previous step (btrfs_log_new_name() only updates the log tree in
   memory);

7) We have a power failure;

8) Next time the fs is mounted, log replay happens and when processing
   the inode for directory "dir1" we find a new INODE_REF and add that
   link, but we don't remove the old link of the inode since we have
   not logged the old parent directory of the directory inode "dir1".

As a result after log replay finishes when we trigger writeback of the
subvolume tree's extent buffers, the tree check will detect that we have
a directory a hard link count of 2 and we get a mount failure.
The errors and stack traces reported in dmesg/syslog are like this:

Fix this by never logging a conflicting inode that is a directory and was
moved in the current transaction (its last_unlink_trans equals the current
transaction) and instead fallback to a transaction commit.

A test case for fstests will follow soon.
