message:
Bug#28870 check that table locks are released/reset
    
The problem is that some mysql_lock_tables error paths are not
resetting the tables lock type back to TL_UNLOCK. If the lock
types are not reset properly, a table might be returned to the
table cache with wrong lock_type.
      
The proposed fix is to ensure that the tables lock type is always
properly reset when mysql_lock_tables fails. This is a
incompatible change with respect to the process state information.
