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().
