Btrfs: Include map_type in raid_bio
Corrent code use many kinds of "clever" way to determine operation target's raid type, as: raid_map != NULL or raid_map[MAX_NR] == RAID[56]_Q_STRIPE To make code easy to maintenance, this patch put raid type into bbio, and we can always get raid type from bbio with a "stupid" way.
