Yan, Zheng 4a77a16b9f Btrfs: Avoid superfluous tree-log writeout
commit 8cef4e160d 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.
