This function provides a lighter weight version of btrfs_map_block(),
just to provide enough info without filling everything of
btrfs_map_block().
But that function is only used for stripe boundary calculation, and now
stripe boundary calculation is all handled inside btrfs_map_bio(), there
is no need to export it anymore.
