Borislav Petkov 9c72ebef5a ide-cd: handle fragmented packet commands gracefully 
There are some devices in the wild that clear the DRQ bit during the
last word of a packet command and therefore could use a "second chance"
for that last word of data to be xferred instead of simply failing the
request. Do that by attempting to suck in those last bytes in PIO mode.

In addition, the ATA_ERR bit has to be cleared for we cannot be sure the
data is valid otherwise.

See http://bugzilla.kernel.org/show_bug.cgi?id=13399 for details.
