Added whitespace to bli_obj_scalar_ routine calls.

Details:
- Added extra spaces to align arguments of
  bli_obj_scalar_init_detached_copy_of(). This misalignment was due to
  the fact that the function was previously named
  bli_obj_init_scalar_copy_of() and the name change, performed in
  b444489f, was done via recursive sed commands which left subsequent
  lines untouched.
