[PATCH] libata-dev: handle DRQ=1 ERR=1 (revised)

Handle DRQ=1 ERR=1 situation. Revised according to what IDE try_to_flush_leftover_data() does.

Changes:
 - For ATA PIO writes and ATAPI devices, just stop the HSM and let EH handle it.
 - For ATA PIO reads, read only one block of junk data and then let EH handle it.
