Kent Overstreet c670509134 bcachefs: Allocator prefers not to expand mi.btree_allocated bitmap ...

We now have a small bitmap in the member info section of the superblock
for "regions that have btree nodes", so that if we ever have to scan for
btree nodes in repair we don't have to scan the whole device(s).

This tweaks the allocator to prefer allocating from regions that are
already marked in this bitmap.
