Log Message:
make ata_xfer's allocated as part of ata_queue and make it include ata_bio;
they are pre-allocated on attach and ata_get_xfer() now never sleep, drop the
pool

modify wd(4) to file the bio requests using the xfers and hence
make it possible to have more than one active I/O request in flight;
ata_bio callback doesn't need to allocate any memory any more,
require it to never return ATACMD_TRY_AGAIN

move lp, badsect, multi from ata_bio to ata_drive_datas, as they are per-drive,
not per transfer

drop unused drv atac_claim_hw/atac_free_hw hooks, and also drop again ata_bio
