description:
two last forgotten on-stack xfers replaced with using the queue xfer -
ata_get_params() and ata_set_mode()
fix wdc_atapi_get_params() to free the xfer used for soft reset before
calling ata_get_params() - it's now necessary, as ata_get_params() doesn't
invent a private xfer own any more
