Problem:
=========
During commit, server calls prepare_commit_versioned to
determine the transaction modified system-versioned data.
Due to binlog_do_db option, we disable the binlog for the
statement. But prepare_commit_versioned() is being
called only when binlog is enabled for the statement.

Fix:
===
prepare_commit_versioned() should happen irrespective
of binlog state. So if the server has any read-write operation
then we should call prepare_commit_versioned().
