System ACE compact flash controller supports either 8-bit (default) or 16-bit data transfers. And in corresponding driver we need to implement read/write of 16-bit data words properly for both modes of operation.

In existing code if width==8 both branches get executed which may cause unexpected behavior of SystemAce controller.

Addition of "else" fixes described issue and execution is done as expected for both (8-bit and 16-bit) data bus widths.
