The array indexes in this function are used with a zero index in the
fv_idx table, and with a +1 index in the lkup_idx arrays. The code
was using the lookup index for the field vector in only one place in
this function, but the code was never used after this point so just
remove the bad line.
This was caught by the undefined behavior sanitizer.
