    internal-fn: Fix bug of BIAS argument index
    
    When trying to enable LEN_MASK_{LOAD,STORE} in RISC-V port,
    I found I made a mistake in case of argument index of BIAS.
    
    This patch is an obvious fix.
    
    gcc/ChangeLog:
    
            * internal-fn.cc (expand_partial_store_optab_fn): Fix bug of BIAS
            argument index.
