Series btrfs: split bio at btrfs_map_bio() time | expand

Commit Message

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.
