libata: don't use on-stack sense buffer
sense_buffer is used as DMA target and shouldn't be allocated on stack. Use ap->sector_buf instead. This problem is spotted by Chuck Ebbert. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Chuck Ebbert <cebbert@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
