export it so we can move things in pieces.

Josef Bacik caa4efafcf btrfs: temporarily export fragment_free_space 
This is used in caching and reading block groups, so export it while we
move these chunks independently.

Josef Bacik 2e405ad842 btrfs: migrate the block group lookup code 
Move these bits first as they are the easiest to move.  Export two of
the helpers so they can be moved all at once.
