Josef Bacik f31f09f6be btrfs: tree-log: make the return value for log syncing consistent
Currently we will return 1 or -EAGAIN if we decide we need to commit
the transaction rather than sync the log.  In practice this doesn't
really matter, we interpret any !0 and !BTRFS_NO_LOG_SYNC as needing to
commit the transaction.  However this makes it hard to figure out what
the correct thing to do is.

Fix this up by defining BTRFS_LOG_FORCE_COMMIT and using this in all the
places where we want to force the transaction to be committed.
