lightnvm: potential underflow in pblk_read_rq()
This is a static checker fix, and perhaps not a real bug. The static
checker thinks that nr_secs could be negative. It would result in
zeroing more memory than intended. Anyway, even if it's not a bug,
changing this variable to unsigned makes the code easier to audit.
