mips/float_dsp: fix vector_fmul_window_mips on mips64
Commit dfa920807494 ("mips/float_dsp: fix a bug in vector_fmul_window_mips") fixed vector_fmul_window_mips by unrolling the loop only 4 times, but also removed the outer C loop and replaced it with assembly branches and pointer arithmetic. When submitting my 64-bit porting patch I missed this new assembly which also needed porting. This patch fixes a bus error in the fate-float-dsp test when run on 64-bit mips.
