misc: fix infinite loop when finding the start of the hugefile start range

When looking for the start of the hugefile range, the 'next' variable
is incorrectly decremented.  If we happened to find a single free
block, the effect of this decrement is that blk == next, which means
that we never modify the loop control variable, so get_start_block
never returns.
