In scan_allocbt, we iterate each free space btree record (of both bnobt
and cntbt) in the hopes of pushing all the free space from UNKNOWN to
FREE1 to FREE.  Unfortunately, the first time we see a free space record
we only set the first block of that record to FREE1, which means that
the second time we see the record, the first block will get set to FREE,
but the rest of the free space will only make it to FREE1.  This is
incorrect state, so we need to fix that.
