In the nand_read_buffer() step, the seed is calculated by doing a modulo
by conf->nseeds which is always zero when not using the randomizer (most
of SLC NANDs).
This situation turns out to lead to a run time freeze.
Derive this seed only when the randomizer is enabled (and conf->nseeds
logically not zero).
