libata: add SG safety checks in SFF pio transfers Abort processing of a command if we run out of mapped data in the SG list. This should never happen, but a previous bug caused it to be possible. Play it safe and attempt to abort nicely if we don't have more SG segments left. Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
