ide: add ide_pad_transfer() helper
* Add ide_pad_transfer() helper (which uses ->{in,out}put_data methods internally so the transfer is also padded to drive+host requirements) and use it instead of ide_atapi_{write_zeros,discard_data}(). * Remove no longer needed ide_atapi_{write_zeros,discard_data}().
