ide-{floppy,tape}: fix padding for PIO transfers
* Return number of bytes left to transfer from idetape_{in,out}put_buffers() and number of bytes done from ide_tape_io_buffers(). * Fix padding for PIO transfers in ide_pc_intr() so read/write buffers are always completely processed and then the transfer is padded if necessary. * Remove invalid error messages. * Remove now superfluous padding from ide{_io_buffers,tape_input_buffers}(). While at it: * Set pc->bh to NULL in idetape_input_buffers() after all bh-s are done. * Cache !!(pc->flags & PC_FLAG_WRITING) in local variable in ide_pc_intr().
