libata: don't check n_sectors during revalidation if zero
If the initial configuration fails early, n_sectors is left at zero. Checking against it during revalidation makes retried configuration fail due to n_sectors mismatch. Ignore zero n_sectors during revalidation. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
