Btrfs: Avoid superfluous tree-log writeout
commit 8cef4e160d74920ad1725f58c89fd75ec4c4ac38 upstream.
We allow two log transactions at a time, but use same flag
to mark dirty tree-log btree blocks. So we may flush dirty
blocks belonging to newer log transaction when committing a
log transaction. This patch fixes the issue by using two
flags to mark dirty tree-log btree blocks.
