    [AArch64] Remove redundant calculation of plt stub destination for veneer
    
    elfNN_aarch64_size_stubs, the caller of aarch64_type_stub has redirected
    the final destination of long branch veneer to plt stub if the call
    should go through it.
    
    It's redundant to do the same check and redirect again from scratch
    inside aarch64_type_stub.
    
    bfd/
      * elfnn-aarch64. (aarch64_type_of_stub): Remove redundation calcuation
      for destination.  Remove useless function parameters.
      (elfNN_aarch64_size_stubs): Update parameters for aarch64_type_of_stub.
