bugfix: TSG-21824 filter service chaining rendered service path (RSP)v1.3.3-20240712

    * 'mirroring block' does not affect RSP
    * 'steering block' terminates RSP

Example:
   Service Function List : A(steering)->B(mirroring block)->C(mirroring)->D(steering block)->E(mirroing)
   Expect RSP            : A->C
