block: limit disk max sectors to (LLONG_MAX >> 9)

Kernel `loff_t` is defined as `long long int`, so we can't support disk
which size is > LLONG_MAX.

There are many virtual block drivers, and hardware may report bad capacity
too, so limit max sectors to (LLONG_MAX >> 9) for avoiding potential
trouble.
