Btrfs-progs: fix infinite loop in find_free_extent

If the found %ins is crossing a stripe len, ie. BTRFS_STRIPE_LEN, we'd
search again with a stripe-aligned %search_start.  The current code
calculates %search_start by adding a wrong offset, in order to fix it, the
start position of the block group should be taken, otherwise, it'll end up
with looking at the same block group forever.
