btrfs: remove btrfs_dio_data::submitted

This member records how many bytes are submitted for a direct
read/write, utilized by iomap_end() callback to handle short IO cases.

However iomap_end() callback is already providing an internally tracked
@written member, which is doing the same accounting and providing the
same value as btrfs_dio_data::submitted.

There is no need to duplicate the work, just remove btrfs_dio_data::submitted.
