bcachefs: Kill bch_write_op.index_update_fn
This deletes bch_write_op.index_update_fn: indirect function calls have
gotten considerably more expensive post spectre/meltdown, and we only
have two different index_update_fns - this patch adds a flag to specify
which one to use (normal vs. data move path).
