Description
1. when mr0=1 case the accumulator register and operand
registers for an fma instruction got swapped. Corrected
the copy paste error.
2. Removed fill array for c_ref in bench_lpgemm.c and used
memcpy from c buf, because fill array now using rand()
function to initialize data which can be different
when c_ref and c called separately, this was working
because data was fixed (i=0 ... i%5).
