[PATCH] internal-fn: Fix bug of BIAS argument index

[juzhe . zhong]

From: Ju-Zhe Zhong <juzhe.zh...@rivai.ai>

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,

Ok for trunk ?

gcc/ChangeLog:

        * internal-fn.cc (expand_partial_store_optab_fn): Fix bug of BIAS 
argument index.
