Well, currently, for libata devices, all passthrough commands bump it
up because the result taskfile is reported via sense data, which is
pretty misleading for something named ioerr_cnt.  Maybe we can ignore
CHECK_CONDITION for ATA passthrough commands but special casing them
can be confusing in other ways.

Thanks.
