Colin Ian King a48faebe65 lightnvm: fix out-of-bounds write to array devices->info[] ...

There is an off-by-one array check that can lead to a out-of-bounds
write to devices->info[i].  Fix this by checking by using >= rather
than > for the size check. Also replace hard-coded array size limit
with ARRAY_SIZE on the array.
