 Description   

After MDEV-3808 we have persistent table metadata versions stored in frm files.
Now we can remove that temporary workaround that uses table_map_id
in TABLE_SHARE::get_table_ref_version(). Using non-persistent versions
causes unnecessary re-prepares of prepared statements, because a table will be
erroneously identified as ALTER-ed when it's simply closed and reopened.
