Coly Li 7e76336e14 badblocks: Fix a nonsense WARN_ON() which checks whether a u64 variable < 0 ...

In _badblocks_check(), there are lines of code like this,
1246         sectors -= len;
[snipped]
1251         WARN_ON(sectors < 0);

The WARN_ON() at line 1257 doesn't make sense because sectors is
unsigned long long type and never to be <0.

Fix it by checking directly checking whether sectors is less than len.
