dm dust: remove redundant unsigned comparison to less than zero
Variable block is an unsigned long long hence the less than zero comparison is always false, hence it is redundant and can be removed. Addresses-Coverity: ("Unsigned compared against 0") Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Bryan Gurney <bgurney@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
