XA COMMIT ONE PHASE self-blocks at rotation #6

This issue only exists in open source version of kunlun-storage.

If binlog rotation is initiated by a XA COMMIT ONE PHASE transaction commit, the worker thread blocks itself.

This is caused by two fixes which make sure XA COMMIT ONE PHASE txns are crash safe. Such fixes are correct but not sufficient --- we have to avoid doing rotation at XA COMMIT ONE PHASE commits.
