[libata] get-identity ioctl: Fix use of invalid memory pointer
for SAS drivers. Caught by Ke Wei (and team?) at Marvell. Also, move the ata_scsi_ioctl export to libata-scsi.c, as that seems to be the general trend. Acked-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
