libata: update ->data_xfer hook for ATAPI
Depending on how many bytes are transferred as a unit, PIO data
transfer may consume more bytes than requested. Knowing how much
data is consumed is necessary to determine how much is left for
draining. This patch update ->data_xfer such that it returns the
number of consumed bytes.
While at it, it also makes the following changes.
* s/adev/dev/
* use READ/WRITE constants for rw indication
* misc clean ups
