Fixed bug in scal2v reference

- When alpha is equal 1 in scal2v the computation can be reduced to
  copyv. The condition check in else if condition has to be a check
  for alpha equal to one and not zero.
- BLIS_NO_CONJ has been passed while invoking copy. In case of single
  and double complex, the appropriate conjx needs to be passed with
  copyv so that the vector can be conjugated before copying to the
  destination.
