Btrfs: don't try to allocate from a block group that doesn't have enough space

If we have a very large filesystem, we can spend a lot of time in
find_free_extent just trying to allocate from empty block groups.  So instead
check to see if the block group even has enough space for the allocation, and if
not go on to the next block group.
