Series btrfs: dynamic and periodic block_group reclaim | expand

This is handy when computing space_info dynamic reclaim thresholds where
we do not have access to a block group. We could add it to the various
functions as a parameter, but it seems reasonable for space_info to have
an fs_info pointer.
